Heavy metal pioneers certainly, but as this appealing history shows, Deep Purple also had the knack of turning a great riff into a decent pop song. There's a dated feel to the lengthy interviews with the likes of Jon Lord, Ian Paice and Ritchie Blackmore, all conducted in the early '90s. But as all but two of the live performances in the archival footage come from 1968-74, it hardly matters.
The new issue of Uncut arrives in UK shops on Thursday, though perhaps a few subscribers, with a prevailing wind, might have already received their copies. Lots of interesting stuff in there, including new interviews with The National, Laura Marling, Deborah Harry and Todd Rundgren; The Eagles, The Waterboys, Deep Purple, Mark Mulcahy, Kurt Vile; reviews of Fleetwood Mac, Vampire Weekend, REM, Van Dyke Parks and Jandek; respects paid to Jason Molina, Andy Johns and Phil Ramone; and a brief exchange with the now notorious Michelle Shocked.
