Full Biography


Provider of artistic content summarizes at best the prolific activities of Dr Robert Casteels, a renowned composer, conductor, educator, pianist, educator and researcher. He believes that these roles are fundamentally interrelated in the kaleidoscope of activities that is music making. 


Music Direction and Conducting

Casteels has conducted more than 50 professional orchestras in 20 countries in a repertoire of 600 works ranging from the early classics to contemporary music, from symphonic to vocal and dance repertoire. He has conducted first performances of symphonic works, ballets and operas in festivals such as: Spoleto Festival (Charleston, US/ Spoleto, Italy/ Melbourne, Australia), Ars Musica (Brussels), Brisbane Biennale (Australia), Focus (New York), Wien Modern (Vienna), Donaueschingen and Berlin Biennale (Germany).

Composition and Arrangement

Casteels is one of those composers whose music makes an immediate impact on the audience. The idea of following tradition, rules and stylistic imperatives is completely foreign to a body of music which really mixes it up. His growing corpus of more than 140 musical works cross cultures, genres and disciplines: 1 opera, 4 concertos, 5 masses, 6 symphonies, 9 works for carillon, 8 works akin to symphonic poems, 9 choral works, 13 chamber music works, 13 electro-acoustic works,14 art songs, 16 instrumental solo pieces, 17 gamelan pieces and 25 ensemble pieces. His compositions range from miniature to large-scale works in the European tradition, as well as multidisciplinary works which combine European, Chinese and Indian instruments, as well as the gamelan, together with computer-generated sound and images. His compositional trademark is the organic combination of European and non-European instruments. Nine audio and two video compact disks entirely devoted to Casteels’ works have been published thus far.


Asian music is one of Casteels’ great passions and sources of inspiration. In 2004, the University of Melbourne awarded Casteels a Doctorate for his thesis on gamelan and contemporary music. As Artistic Director of the Asia-Europe Foundation’s (ASEF) 1st music camp I’mPulse held in the Philippines in 2005, he conceived and executed an initiative which brought together young graduates from the universities and conservatories of 35 ASEF countries to perform and record each others’ works. In 2008, Casteels conducted ASEAN Serenade, an evening of music, song, dance and poetry from each ASEAN country in homage to National Cultural Medallion winner, Mr Alex Abisheganaden. In 2009, 2010 and 2012, Casteels released four CDs and a dvd entitled ‘Resonances of Asia’, bringing the listener on an aural journey through China, India, Japan, Java, Korea, Philippines, Mongolia, Myanmar, Thailand and Vietnam.


Chronologically, the compositional output of Robert Casteels can be divided into three periods: 14 opus numbers, mostly atonal, composed in Belgium, his country of birth, from 1981 to 1988, followed by a gap of seven years of compositional silence, then -coinciding with his arrival in South-east Asia- a second period from 1995 to 1999 with 19 opus numbers focused on spectral music and gamelan, followed by a silent year in 2000, and since 2001 a third period of 110 compositions, mostly modal or poly-modal. His compositions have been premiered or performed in Australia, Belgium, China, England, Indonesia, Japan, Korea, Malaysia, New Zealand, the Netherlands, the Philippines, Singapore and Vietnam.

Whilst continuing his conducting engagements on the international stage, Casteels shifted the focus of his activities from Europe to Australasia, choosing Singapore as his home base in 1995, and taking up permanent residency in 1996 and accepting citizenship in 2007. In 2021, Casteels was the only musician featured in a book entitled Stories of Integration published by Marshall Cavendish, about thirty Singaporeans who made an impact. He has contributed tirelessly to Singapore’s music scene. Casteels has served as Dean of the Faculty of Performing Arts at the LASALLE-SIA College of the Arts (LASALLE), as a member of various competition jury panels and government-appointed arts and education committees, as Music Director of the Singapore National Youth Orchestra (SNYO), as Founding Artistic Director & Resident Conductor of the Philharmonic Winds, as Music Director & Conductor of the National University of Singapore (NUS) Choir, NUS Wind Symphony and the NUS Guitar Orchestra (GENUS), as guest conductor of the Yong Siew Toh Conservatory of Music Chamber Singers and New Music Ensemble. 


Casteels’ achievements include producing SNYO’s first cd recordings of professional quality as well as conducting SNYO’s debut at the Esplanade Concert Hall, producing GENUS's first cd recording. He has premiered iconic masterpieces in Singapore, such as works by Boulez, Ligeti, Takemitsu, Stockhausen and Varèse. He champions the works of his fellow Singaporean composers by organizing and conducting successful concerts entirely devoted to emerging Singaporean composers and by regularly including Singaporean works in concerts of standard repertoire. 'Pictures at an (SG) Exhibition' was a special project that Casteels conceived and executed in October 2019 in collaboration with the National Gallery Singapore: ten young Singaporean composers were commissioned to compose a new piece of chamber music inspired by Singaporean paintings belonging to the collection of the National Gallery. The compositions were premiered next to the paintings, recorded and published. This project was followed in 2021-2022 with  'Pictures at an (SEA) Exhibition': six established Singaporean composers were commissioned to compose a new piece for vocal ensemble a cappella inspired by South East Asian paintings belonging to the collection of the National Gallery. The compositions were premiered next to the paintings, recorded and published.


Casteels has collaborated with more than 50 Singaporean visual and performing artists, and was co-founder of the LASALLE Gamelan Ensemble, which has performed in New Zealand, Australia and Indonesia. In 2005, he led the Philharmonic Winds to win the Gold with Distinction Award at the World Music Contest of Kerkrade (The Netherlands) with the highest mark ever scored by a Singaporean group. In 2007, Casteels became a proud Singaporean citizen, focusing his activities on composing and teaching.


As a much sought after chamber music pianist and vocal accompanist, Casteels has performed with many instrumentalists, singers and co-pianist Shane Thio. Productions as pianist/musical director include: An Evening of Love Songs, the musical Oliver Twist, pOpera part for Flip Side in conjunction with the Singapore Arts Festival 2009, La Belle Epoque, an evening of European operettas and art songs at the turn of the 20th century, Another Murder on the Orient Express, Not Quite the Moulin Rouge…, An Evening at the Opera, George and the Music Box and The Scent of Josephine Baker.


Special Projects

In 2004, Casteels was appointed the first Associate-in-Residence (Special Music Projects) by the NUS Centre for the Arts. He initiated, raised funds and executed a series of special projects that combined music and other disciplines in a meaningful collaboration between international and Singaporean artists: ‘the Magic of Music in Movies’ in 2004, ‘Music and Architecture’ in 2006, ‘Food, Plants and Music’ in the Arts House at the Old Parliament and Petronas Galeri in Kuala Lumpur in 2007, 'Music and Birds' in 2009  in collaboration with the Singapore Botanic Gardens’ 150th Anniversary celebrations, in 2011 in collaboration with Yong Siew Toh Conservatory of Music and in 2015 in collaboration with SG50, 'Music and Finance' in 2011, 'Music and Astronomy' as well as 'Music and Medicine' in 2012. Floating Lighthouse with light designer Ryf Zaini and visual artist Milenko Prvački in 2019. 'Hearing Images&Seeing Sound' is a 2016 transdisciplinary project conceived by Robert Casteels and funded by the Creation Grant of the National Arts Council. This research project brought together visual artists Milenko Prvački and Joshua Yang, videographer Hilmi Johanna, electro-acoustician and e-luthier Dirk Johan Stromberg, composer and conductor Robert Casteels as well as singers Evelyn Ang, Angela Cortez, Melissa Estrella, Daniel Ho, Jeremy Koh, David Ng, Leslie Tay and Felicia Teo. The research culminated into a performance evening that took place in December 2016 in the Dhoby Ghaut Visual Arts Centre followed by an eponymous exhibition. A 77-page catalogue published was in March 2017. A continuation and expansion of this transdisciplinary project took place in April 2019 under the title ‘time:crystals’ with the creation of Nine Dragons with videographer Cécile Chagnaud. 'Pictures at an (SEA) Exhibition' was a special project that Casteels conceived and executed in April 2022 in collaboration with the National Gallery Singapore: six established Singaporean composers were commissioned to compose a new piece of a cappella music inspired by South East Asian paintings belonging to the collection of the National Gallery. The compositions were premiered next to the paintings, recorded and published.


The year of 2013 was dominated by the premiere of his first opera De Kaartridder, commissioned by the city of Landen in Belgium to celebrate the 800th anniversary of its founding. The main theme of De Kaartridder (meaning the Knight with the cards) is gambling. The protagonist is a 120-strong chorus. In 2013 Casteels composed for the first time for carillon, an ubiquitous instrument that is part-and-parcel of the sonic landscape of every city of Flanders. To date, eight works for carillon were premiered in Leuven and Tienen, his city of birth. A cimbined score was published in 2021.


The year of 2014 marked his debut in Japan where he conducted Semisopochnoi concerto for electric guitar, Cityscape for guitar orchestra and electro-acoustic sounds, as well as the premiere of his symphonic poem Kaze Ni Noru by the Tokyo Philharmonic Orchestra under his direction, as part of the 32nd Asian Composers League Festival & Conference. His ritual music entitled Sälapa on Pala’wan poetry was selected by the 33rd Asian Composers League Festival & Conference in the Philippines to close its final concert. Casteels conducted the premiere of Cu Rua for dan bau and orchestra for the opening concert of the 34th Asian Composers League Festival & Conference in Hanoi, Vietnam.


The year of 2015 witnesses the premiere of fourteen new compositions for organ, piano and two pianos, orchestra and ensemble. Flautist Roberto Álvarez and harpist Katryna Tan performed 'Nachtlied' by Casteels during their 2015 Australian concert tour. The Philharmonic Winds created Hanging Gardens for large wind orchestra, processed sounds and video.


Casteels has always been interested in new media: in 2010 in his piece entitled Simple-X created with violinist Seah Huan Yuh, performers played their instruments whilst triggering off additional sounds using iPads. The use of this gadget in concert was then an innovative premiere for Singapore and the region. With electro-acoustician Dirk Stromberg and art director Andrew Thomas, Casteels has created an ambitious one-hour epic with newly created e-instruments engaging in a musical dialogue with electro-acoustic sounds, dance and stunning visuals. This research entitled '2014:time:space:' culminated into a mind opening performance in the FlexiSpace of LASALLE College in 2014. New expanded versions were presented in the ArtScience Museum (2015), during the 7th Duong Dai Festival in Hanoi (2015), as finale of the closing concert of the International Meeting temp’Ora in Bordeaux, France (2016), in educational institutions such as NUS, SOTA, Eunoia and National Junior Colleges and the Lycée Français, Singapore (2017 and 2018).


In 2020 Casteels conceived, executed and directed an ambitious project that was entirely digital. ¿Rəsiliəncəproject sonically and visually echoes our individual responses to the sanitary, ontological and teleological crisis of COVID-19 that has affected all of us worldwide. Ewing Tejas and Deepesh Vasudev created original movies on Casteels‘s sound track. Five soloists, a writer and dancer responded to sections of sound track. This collaborative journey resulted into nine episodes that were premiered online each Thursday in October and November 2020. Given its sucess, ¿Rəsiliəncəwas performed live in July 2021. In 2021 Casteels conceived and executed the digital project entitled Bubbles first in September 2021 in direct interaction with musicians performing in his city of birth Tienen, then in October 2021 in direct interaction with dancers performing in Australia (as part of an e-residency Australia-Singapore). The screening of the latter project was repeated in March 2022 as part of the BOLD22 Festival in Australia. 

September and November 2021 saw the premiere of the mixed media project entitled Acqua nel Riflesso. NUS opened its annual arts festival, NAF 2022, with a dance production entitled Incandescent - A City that Never Sleeps on a choreogaphy by Yarra Ileto and on music by Casteels. Subsequently, this work was awarded ‘Best 2022-2023 production’ by the National University of Singapore.


Casteels has composed for silent advertising movie (2011, Swiss Business Association Singapore), silent art movie (2011, National Museum Singapore) and for a film on forest fires (2014, Kyoto).
