by Alex HendersonDeep Purple went through more than its share of personnel changes over the years. In 1990, its lineup consisted of guitarist Ritchie Blackmore (who had returned after leaving in 1974), singer Joe Lynn Turner, keyboardist/organist Jon Lord, drummer Ian Paice, and bassist Roger Glover. Longtime Purple followers hoped that Blackmore's presence would enable the band to reclaim the metal throne, but Slaves and Masters was hardly the album to do it. The songwriting is weak and pedestrian, and most of the time, the once-mighty Purple (which was at least 16 years past their prime) sounds like a generic Foreigner wannabe. Even Blackmore's input can't save this consistently disappointing CD, which only the most thorough collectors will want.
