Deep Purple - Deep Purple In Rock

With In Rock, Deep Purple added vocalist Ian Gillan into the lineup, a decision that irrevocably changed their fortunes. In Rock is one of the genre's definitive albums, combining hard-edged riffs with virtuoso technique, topped by Gillan's full-throated roar. Few singers could survive the instrumental power beneath him, but this he does with room to spare, reacting to and emphasizing his colleagues' musical prowess. Chock-full of material destined to become Deep Purple anthems, later releases were evaluated against this trail-blazing, heavy rock collection.
