The result generated much controversy, as the band was hardly considered "hard rock," let alone "metal," even by themselves. they beat out heavily favoured bands such as Metallica and Jane's Addiction. also, When Metallica did win a Grammy in 1992 drummer Lars Ulrich referenced the previous award by facetiously "thanking" this band for not putting out an album that year! who?

Jethro Tull won the 1989 Grammy Award for Best Hard Rock/Metal Performance, controversially beating Metallica's '...And Justice for All.' This decision was widely criticized as Jethro Tull is a progressive folk-rock band, not a hard rock or metal act. In 1992, when Metallica finally won a Grammy, drummer Lars Ulrich famously 'thanked Jethro Tull for not releasing an album that year,' referencing the controversial 1989 decision. Bruce Springsteen, Deep Purple, and Santana were not involved in this specific Grammy controversy.
