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 various 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 obtained 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 and guest with orchestra at the International Cello Festival in Rutesheim. William’s progressive compositions have received praise from distinguished artists including Giovanni Sollima.

Since the release of his collaborative debut single “Keep Away” with percussionist Sami Butler, he has continued to pursue a passion for producing new music. William moved to London to base himself as a freelance British/Australian performer in 2018. William aims to expand the musical capabilities of his instruments and break down barriers between genres and cultures.
