In their first four years together, Alice Cooper evolved from the psych-tinged hard-rockers that recorded 1969's Pretties For You to the schlock-horror provocateurs of I'm Eighteen and School's Out fame. On record, they honed their sound for maximum impact, each new release taking them further up the charts in gleeful defiance of the moral majority's outcries. Live, they channelled their outre impulses into bloodthirsty stage shows, Glen Buxton's buzzsaw guitars threatening to do more damage then the various contraptions which were routinely brought onstage to mock-execute their frontman.
Soon, they would implode, but as Concert Broadcasts 1969-1972 makes perfectly clear, with classics such as Elected, Black Juju and Under My Wheels in their arsenal, Alice Cooper could slay any audience.
