History of Metal -> Black Sabbath, Led Zeppelin, Aerosmith, The Scorpions, UFO, Judas Priest in the beginning Then NWoBHM, shred and glam, in the '80s '90s, Black Metal? '00s, look around I really don't know :lol: Epic fail :lol: I hope you fail/failed that assignment. Zeppelin, Aerosmith, and Scorpions are NOT metal. 80s: Power Metal? Thrash? 90s: Progressive Metal? Nu Metal also began in the 90's. :/
