Jason Willett is an American musician, known largely for his work with experimental rock groups including Half Japanese, Can Openers, Pleasant Livers, X-Ray Eyes, The Dramatics, The Jaunties, The Attitude Robots, Leprechaun Catering and many more. His record label, Megaphone, initially set out to issue work by punkish Rock in Opposition-derived performers like The Work, Fred Frith, the Molecules, Tim Hodgkinson and Jac Berrocal but became largely a venue for Willett's own collaborative music.
