Operation Ivy was an influential ska punk band formed in the East Bay region of the San Francisco Bay Area. The band consisted of frontman Jesse Michaels (vocals), Tim Armstrong (credited as "Lint") (vocals/guitar), Matt Freeman (credited as Matt McCall) (bass/backing vocals), and Dave Mello (Drums/backing vocals). The band's name, previously abandoned by another Gilman group, Isocracy, was derived from the Operation Ivy series of nuclear tests. [1]
