Attention, Deep Purple fans: It’s almost time. On June 28, the British metal band will release their much awaited ‘Phoenix Rising’ documentary -- a two-hour opus packed with 30 minutes of previously unreleased onstage footage from Japan. The documentary will be available on DVD, Blu-ray and in a two-disc DVD/CD package.

What makes this DVD so distinct? Well, as any respectable fan knows, Deep Purple are a secretive crew. ‘Phoenix Rising’ offers rare content and bonus interviews designed to show die-hards a never-before-seen side of the guys. That means interviews with keyboardist Jon Lord and bassist Glenn Hughes, telling the story of Deep Purple from cradle to grave and back again, including the tragic, band-halting loss of Tommy Bolin to heroin addiction.

As for the 90-minute documentary section, ‘Getting Tighter,’ a statement from the band says it will recount “the trials and tribulations of a band in turmoil, riding the rock 'n' roll roller coaster to total excess.”

Music-wise, expect eight songs from a July 1976 performance: 'Burn,' 'Getting Tighter,' 'Love Child,' 'Smoke On The Water,' 'Lazy,' 'Homeward Strut,' 'You Keep On Moving' and  'Stormbringer.'

Deep Purple devotees who would rather see the guys in the flesh should note the band’s current symphonic tour, which finds the band augmented with string and horn sections.
