Evan Parker (born 1944) is a British free jazz saxophone player.
He has recorded dozens of albums solo or as a group leader, and has recorded or performed with Peter Brotzmann--including Brotzmann's epochal "Machine Gun" in 1968, Derek Bailey, Keith Rowe, Joe McPhee and many others.
In recent years, Parker has expanded beyond free jazz, working with the dub music oriented Jah Wobble and the adventurous drum n bass duo Spring Heel Jack.
Parker is one of rather few saxophone players who has extensively recorded and performed unacompanied, and has developed a unique, idenitifiable approach. One critic has written that Parker's solo performances "reveal also the mechanical possibilities for the instrument that weren't even considered before he came along — things like playing in all three registers of the instrument at the same time.
