18. Tyr (1990)

You only need to read a description of Tyr to see things were headed in the wrong direction: Black Sabbath toying with Norse mythology, just a few years before a bunch of sociopathic Norwegian kids did more interesting things with their native folklore. It’s a forgettable album that often sounds like Styx trying to record a full on rock opera a la Kilroy Was Here. Iommi’s riffs are buried; the keyboards run ramshackle and the concept and approach were ham-handed at best. TYR is ample proof that even lord of riffs Tony Iommi makes mistakes; in his memoir he titled the chapter on this era “TYR And Tired.”
