The Sabbath album that silenced all doubters. "Not satisfied after merely heavy metal in 1970, Black Sabbath returned in 1971 to root out the music's soul. "Master Of Reality" reeks of dungeons, chains, and sweet, ancient smoke. Beneath the armor, this is the essence of anguish- Black Sabbath at their holiest"- Ian Christe, author, Sound Of the Beast: The Complete Headbanging History Of Heavy Metal. "Black Sabbath grind out riff after riff after unrelenting riff; even the guitar leads are riffs, and there isn't one excessive uncalled-for guitar lead on their whole new album"- Metal Mike Saunders, 1971.
