642 - Black Sabbath Voodoo 1981

"Mob Rules", Black Sabbath's tenth studio album and second to feature former Elf/Rainbow vocalist Ronnie James Dio, sees the band making some changes from it's predecessor, "Heaven and Hell." Most noticeable is the addition of drummer Vinnie Appice, who replaced original drummer Bill Ward. Musically it seems the band is going for faster numbers and tighter song arrangement, although there is no lack of Sabbath's trademark gloom and doom. “Voodoo” has an excellent and catchy riff, perfect bass lines, Dio’s excellent vocal performance and a good solo.
