Maynard James Keenan
Trent Reznor
Brian Warner
-The last 2 are from trendy goth rock bands ( more Brian then Trent ) but are both very underrated
Mikael Akerfeldt- Give a listen, very powerful, dynamics are nearly unmatchable.
Chris Cornell
Eddie Vedder
-Both appeared on the scene at generally the same time, both very passionate singers, Chris has the upper hand though, his range is incredible.
