Callum O’Reilly is an Australian composer, multi-instrumentalist, and multimedia artist whose work spans film, concert music, and immersive sound art. Known for pushing the boundaries of traditional classical ensembles, his music blends orchestral writing with electronic music, hip-hop, pop, and modern jazz, creating contemporary sonic worlds that echo the musical legacy of the past. Zen Buddhist philosophy and aesthetics often inform his creative practice.
Alongside an extensive career in concert music—working with ensembles such as the Sydney Symphony Orchestra, Western Australian Symphony Orchestra, and Australian Youth Orchestra—O’Reilly is increasingly active in screen and theatrical projects. He composed the score for the Australian short film The Worm, which premiered at the 2026 Sundance Film Festival.
