Hot on the heels of Rhino Records' acclaimed 4-CD Shades box set, comes this newly digitally remastered Deep Purple classic, featuring the band's definitive line-up of Ritchie Blackmore (guitars), Ian Gillan (vocals), Jon Lord (keyboards), Roger Glover (bass) and Ian Paice (drums). Includes "Knocking at Your Back Door" and "Perfect Strangers," plus the bonus track "Son of Aleric" - the complete 10-minute instrumental tour-de-force, previously unavailable on CD!
