William Parker deserves a Pulitzer Prize, or at least a MacArthur Fellowship. His body of work is nearly 50 years deep at this point, and encompasses vocal and instrumental music (his own original compositions, and brilliant reinterpretations of others’ work), poetry, criticism, and journalism. His long-running bands the William Parker Quartet and its expanded incarnation Raining On The Moon; In Order To Survive; and the Little Huey Creative Music Orchestra are balanced by short-lived or one-off ensembles that may only appear for a single album or concert. In addition to work under his own name, he’s been a key member of groups led by Cecil Taylor, Peter Brötzmann, Bill Dixon, David S. Ware, Matthew Shipp, and others. Although his work hinges on a deeply individual voice, he is a community builder at heart. He and his wife, Patricia Nicholson, have run the annual Vision Festival in New York for over 20 years, and that single annual event has grown to encompass multiple performance series running all year long, many of them outdoors and free, an invitation to the public to experience high-level out jazz as just one more form of art, as physically as it is aesthetically accessible.
