I only really knew the hits off this album: Paranoid, War Pigs/Luke's Wall, and Iron Man. But I was pleasantly surprised to listen to the rest. Planet Caravan is a soft instrumental groove that I would never have expected to hear, and I love the contrast it brought to the album along with other, softer sections like the beginning of Jack the Stripper/Fairies Wear Boots. Ozzy's voice is perfect for the band's sound and subject matter; for me it brings to mind a wailing proselytizer. The drummer is great, and I think his part elevates the music significantly. Rat Salad was fine but stood out a bit from the rest of the album as something you might want to hear live but doesn't beg a second listening.
