This album is definitely a lot better than the previous Sabbath albums with Tony Martin. The addition of Geezer Butler on bass seems to light a fire under Iommi's ass, because each track on the album has something to offer. The riffing is quite memorable, especially on "I Witness", "Psychophobia", "Virtual Death" and "Cardinal Sin." Geezer and Tony have a chemistry that occurs when they play together, and it is very evident on this album.
