Hank Roberts is an American jazz cellist and vocalist who emerged from the US jazz and improvised-music scene in the 1980s and has worked across jazz, avant-garde and folk-influenced genres. His work blends jazz improvisation with elements of folk and rock, often placing the cello in a lead melodic and textural role while incorporating extended techniques, vocalisation and occasional looping, reflecting a career-long interest in expanding the instrument's role within contemporary improvised music.
