The Grammy Awards is an annual ceremony, where honors in several categories are presented by The Recording Academy of the United States to "honor artistic achievement, technical proficiency and overall excellence in the recording industry, without regard to album sales or chart position".
[2] The Recording Academy recognized heavy metal music artists for the first time at the 31st Annual Grammy Awards (1989).
The category was originally presented as Best Hard Rock/Metal Performance Vocal or Instrumental, combining two of the most popular music genres of the 1980s.
This choice led to widespread criticism of The Recording Academy, as journalists suggested that the music of Jethro Tull did not belong in the hard rock or heavy metal genres.
The awards were presented for the song "One", a cover version of Queen's "Stone Cold Crazy", and the album Metallica.
