Deep Purple

Twenty-first studio LP arrives in August.

He's the quintessential frontman, a big-maned, big-voiced singer with a revolving cast to support his personal vision.

Deep Purple's Mk. I released their final album on June 21, 1969.

What fans saw wasn't anything like the band's promised 25th anniversary celebration.

He actually submitted a resignation letter to the band while still on tour promoting 1973's 'Who Do We Think We Are.'
