More than 25 years after the release of WE SOLD OUR SOUL FOR ROCK 'N' ROLL, that excellent Black Sabbath collection is finally eclipsed by SYMPTOM OF THE UNIVERSE, a two-disc compilation that literally doubles the classic metal dosage. Along with every song on WE SOLD OUR SOUL, this remastered set includes 15 more tunes by the original lineup of Ozzy Osbourne, Tony Iommi, Geezer Butler, and Bill Ward. The finest of these additions include the previously U.K.-only track "Evil Woman," the epic stomps "Into the Void" and "Lord of This World," the thunderous "Supernaut," and the driving title track.

SYMPTOM also features "Warning" and the string-laden instrumental "Laguna Sunrise" from the initial two-LP version of WE SOLD OUR SOUL, as well as four tracks from Sabbath's oft-maligned late-1970s albums. The result is an outstanding overview of Ozzy's years with Sabbath, showcasing how his distinctive vocals meshed with Iommi's formidable riffs, Butler's rumbling bass, and Ward's spot-on drums to create music that is unendingly influential.
