According to Revolver Magazine (by way of SMN News), they have published a list of the “50 Heaviest Bands Ever” and man there are gonna be some wild scraps over this sucker. You can find the complete list here but for those of you dying to know, here is the top 10:
1. Black Sabbath
3. Led Zepplin
8. The Melvins
I find it hard to believe that Sabbath is considered heavier than a band like Kyuss or Meshuggah although at least Ozzy could sing (kind of).
