Twenty years ago today, on December 22, 1985, Dennes Dale Boon was killed in a car wreck in the Arizona desert. Singer for the Minutemen, political activist, writer of antiwar songs, enemy of Reagan’s America, D. Boon spoke most eloquently through his guitar. Most punk guitarists hid behind distortion and power chords. D. Boon plucked and picked notes straight to his amp. It sounded more like Thelonious Monk’s late-40s piano than anything punk or rock has ever produced. It also often sounded like he was strangling a chicken. And it’s still beautiful.
