Query: Disappointing follow-up to Purpendicular

when guitarist Ritchie Blackmore was replaced by ex-Dregs Steve Morse, a breath of fresh air blew through the tired old retread that was Deep Purple. The album, Purpendicular, was refreshingly different and diverse. Abandon, in contrast, ias a disappointment -- a return to the same old atavistic stodge. Forgettable.
