(long bio – for programs)

William Jack is an Australian Cellist, Guitarist and Songwriter who explores multiple genres and styles. He began performing from a young age as a virtuosic guitar soloist with Adelaide orchestras and rock bands. He later studied jazz guitar with Mike Bevan and obtained numerous ensemble opportunities, including a scholarship to the Julliard Winter Jazz School.

William studied cello at the Sydney Conservatorium of Music with Georg Pedersen. He pursued further study in Vienna with Maria Sellner at the Universität für Musik und darstellende Kunst Wien. William’s classical music engagements have been extensive and included prestigious venues, from the Musikverein Golden Hall to Sydney Opera House. He has received various awards and guidance from notable artists, such as David Geringas, Thomas Demenga, Natalie Clein and Wen-Sinn Yang. William’s niche is his ability to incorporate his guitar background into an unconventional style of cello playing. He performed twice as a Jazz cello soloist at the International Cello Festival in Rutesheim. William’s progressive works have received praise from distinguished composers, including Giovanni Sollima and Matthias Bartolomey. In 2023, William was selected to perform as a ‘New Folk’ songwriter at the Kerrville Folk Festival in Texas.

William moved to the UK in 2018 to base himself as a freelance touring musician. He has been fortunate to work with numerous world-renowned artists, including Tom Rosenthal, Joseph Lawrence, Fryars, Dan G Sells (The Feeling) and Hari & Sukhmani. During 2019, he co-wrote a debut instrumental project in collaboration with British Franco-Chinese violinist, Laure Chan. The music combines elements of jazz, rock, blues, latin and folk into a classical fusion sound world. Their record generated support from Universal Music and Audio Network during 2020.

The record is inspired by folk music from the around the globe, and tailored for diverse audiences to experience a fresh take on the instrument. An album enriched in traditions, but not encumbered by them. 

2024 will mark the release of William’s sophomore album.
