Black Sabbath: 10 Most Underrated Songs

Towards the midpoint of the '70s, Sabbath had gotten tired of being themselves for a while. After coming off of a massive tour to promote Vol. 4, Tony Iommi finally came to the studio to work on material for the next record, only to come up with nothing. Though inspiration would eventually arrive in spades on Sabbath Bloody Sabbath, the prized cut was actually a bit further down the record.

Compared to the more lethargic tunes in the Sabbath catalog, Sabbra Cadabra actually starts off pretty peppy, almost as if it's a demented take on a blues shuffle. However, the real interesting part is saved for the midpoint, where the entire track opens up to a prog rock section, complete with some of the most outlandish keyboard sounds you've ever heard.

Needing someone else to perform the midsection of the tune, Sabbath enlisted the help of seasoned prog rocker Rick Wakeman, whose soulful playing is about as mystical as the capes that he would often wear when on tour with his band Yes. While Metallica eventually did their take on this song on Garage Inc., their omission of the greatest part of the tune seems like such a missed opportunity in retrospect. Just when you thought that Sabbath had started to reach the end of the line, Sabbra Cadabra proved that there was no real limit to where Iommi's mind would go.
