Yes it wasn't the greatest work of Sabbath. I guess it's one of those lost albums of Sabbath's career.
When I was learning all the great rock of the seventies Sabbath was one of them next to Zepp.
Toni did come up with some real great riffs. He's an underestimated guitarist. I really liked his lead work on War Pigs. Fairy's wear Boots is another one I like. Symptom of the Universe was great too. When I had a band called Engine Room we use to play alot of Sabbath my drummer use to really go off on Symptom of the Universe. I use to hit the chords and wait while he would do the fills. I'd just watch him and enjoy him mimick Bill Ward's fills.........at times when me, the bassist and the drummer would lock-in together.....Symptom was like flying on a Jet-plane!!!!
