S4·E3 Deep Purple: Machine Head

The 1972 early metal classic is examined here. After a brief recount of Deep Purple's history prior, all five members of the group from that time recount the making of the album, and Jon Lord, Richie Blackmore, and Roger Glover isolate some of their parts, and play along live. Engineer Martin Birch also lends a hand, describing how the instrumental sounds were produced.
