Minutemen were an American punk rock band formed in San Pedro, California, in 1980. Composed of guitarist/vocalist D. Boon, bassist/vocalist Mike Watt, and drummer George Hurley, Minutemen recorded four albums and eight EPs before Boon's death in an automobile accident in 1985; the band broke up shortly thereafter. They were noted in the California punk community for a philosophy of "jamming econo"—a sense of thriftiness reflected in their touring and short, tight songs, and for their eclectic style, drawing on hardcore punk, funk, jazz, and other sources.
