Dave mentoned that Jethro Tull won the heavy metal grammy this year (89) -- - I seem to recall hearing some actual booing coming through on the TV when this happened. From JTull's wiki entry:
In response to the criticism they received over the award, the band took out an advertisement in a British music periodical with a picture of a flute lying amid a pile of iron re-bars and the line, "THE FLUTE IS A HEAVY METAL INSTRUMENT."[10] In response to an interview question about the controversy, Ian Anderson quipped, "Well, we do sometimes play our mandolins very loudly."
