Peter Brötzmann is one of the most prolific and enduring of the free jazz musicians to emerge from the European avant music scene of the 1960s. His rough tone and emotively ferocious method of attack on saxophones, clarinet, and taragato are among the most recognizable in jazz. He has played on literally hundreds of recordings, from solo concerts to large ensemble dates and virtually every configuration in between. His continued relevance with generations of players from his bandmates in Last Exit, to Evan Parker, Jim O'Rourke, Keiji Haino, Han Bennink, and Heather Leigh, is rooted in the constant pushing of his own boundaries rather than a "refinement" of his art.
