Come across some old stuff I havent seen in years on Youtube.
70's Judas Priest. Rob Halford was one of the greatest singers out of that era.
80's Queensryche. One of the best bands ever IMO and most likely the best singer out of that era. Cant think of anyone that can touch the range of Geoff Tate. They were amazing. Up there with the likes of Metallica and Iron Maiden. Better than Metallica IMO though.
