Evan Parker (born 5 April 1944 in Bristol) is a British free-improvising saxophone player. His original inspiration was Paul Desmond, and in recent years the influence of cool jazz saxophone players has again become apparent in his music — there are tributes to Warne Marsh and Lee Konitz on Time Will Tell (ECM, 1993) and Chicago Solo (Okkadisk, 1997). However, Parker is probably better known for his 1960s work, which rapidly assimilated the American avantgarde — John Coltrane, Pharoah Sanders, Albert Ayler and others — and forged his own, instantly identifiable style.
