Aaron Cassidy is an American composer and conductor. After 15 years of living and working in England, in 2022 he relocated to Germany, which had increasingly become the base for much of his conducting activity. He lives in Berlin and works as Professor of Composition at the Hochschule für Musik, Theater und Medien Hannover, where he also serves as Director of Incontri—Institut für neue Musik.
As a composer, he is best known for his influential work with multicolored, graphical, tablature notations that prioritise the physical, bodily, and mechanical aspects of sound-production in music, alongside his more recent work exploring the notation of ‘non-geometrical’ rhythm, which untethers speed, duration, and meter from traditional concepts of pulse. Recordings of his work are available on 12 commercial CD releases from NEOS, Kairos, NMC, HCR, and New Focus Records, and his compositions have been presented in hundreds of performances across 29 countries at festivals including Donaueschingen, Ultraschall, Warsaw Autumn, Huddersfield, Darmstadt, Gaudeamus, Dark Music Days, Music Biennale Zagreb, Bludenz, Mixtur, and Tage für Neue Musik Zürich, and at important venues for new music including Southbank Centre London, Miller Theatre, National Concert Hall Taipei, and the Melbourne Recital Centre.
Aaron’s work as a conductor is stylistically diverse, encompassing both contemporary and historical repertoire across orchestral, operatic, chamber, and choral settings. He has led many dozens of world premieres, including work by Richard Barrett, Mary Bellamy, Ann Cleare, Nomi Epstein, Turgut Erçetin, Lucia Kilger, Dariya Maminova, Sergej Newski, and Erik Oña, as well as several of his own compositions. Through the pandemic period he built a strong reputation for his ability to learn challenging repertoire quickly as a last-minute jump-in for numerous high-profile performances. Notable appearances as a conductor include performances with Ensemble Musikfabrik in the Großer Saal of the Berlin Philharmonie for Musikfest Berlin; ensemble mosaik in works by Laura Bowler, Sara Glojnarić, and Sergej Newski at MaerzMusik; ELISION and violinist Harry Ward (Berlin Philharmonic) in the Australian premiere of Liza Lim’s Extinction Events and Dawn Chorus at the Melbourne Recital Centre; and as Musical Director for Ann Cleare’s opera The Little Lives at the Munich Biennale with Ensemble Musikfabrik. He has recorded as a conductor for Kairos, HCR, and Wergo.
