I never liked Tull and thought it was a joke years ago when they won over Metallica for best metal and such...
The catagory was hardrock/heavy metal, poor decision that is was to give Tull credit 20 years into their career or personal taste and opinion aside that award was not strictly the property of "metal". That is what people wishing to ride that bandwagon need to understand.
The year was 1989 and these were the nominations
Best Hard Rock/Metal Performance - Vocal or Instrumental
Jethro Tull - Crest of a Knave
Metallica - And Justice For All
AC/DC - Blow Up Your Video
Iggy Pop - Cold Metal
Jane's Addiction - Nothing's Shocking
many Tull people do not consider Crest to be one of their better works
And Justice for All is considered by many including Metallica to be one of the poorest recording quality production
perhaps neither band deserved a nomination to begin with in this year
had the big Metallica outcry not started over this its doubtfull they would have gotten an award the following year and would have had to wait another 10-15 years like most others in the business who are not directly involved in pop.
The following year they realized having hardrock and metal together was not going to work out
1990 and the nominations looked like this
Best Metal Performance - Vocal or Instrumental
Metallica - One
Dokken - Beast from the East
Queensryche - I Don't Believe In Love
Faith No More - The Real Thing
Soundgarden - Ultramega O.K.
Im not sure picking anything from And Justice for All over anything from Operation Mindcrime showed anything but catering to the previous years outcry. There can be no question which way I would have voted.
