Deep Purple: David Coverdale (vocals); Ritchie Blackmore (guitar); Jon Lord (keyboards); Glenn Hughes (bass, background vocals); Ian Paice (drums). Recorded with the Rolling Stones mobile unit in Montreux, Switzerland in November 1973. The first Deep Purple album to feature Glenn Hughes and David Coverdale, resulted in a much more bluesy effort all round. Coverdale's throaty roar, combined with Hughes' soaring vocal, made for a heartfelt, rootsy record. 'Might Just Take Your Life' was a hit single, and the album featured a series of extended jams, which worked most spectacularly with the elongated 'Mistreated', later resurrected by Coverdale as a live favourite with Whitesnake. The title track and 'Lay Down, Stay Down' gave vent to their more familiar refrains and emphasized the strength of their songwriting.
