I'm feeling old and stodgy and want to liven up my musical existence with a little metal. Problem: all of the bands I find with good bassists have some garbled screaming and/or heavy-breathing lead howler which makes the music hard for me to listen to. I like stuff like old Metallica, Rush (not metal, I know), Living Colour, and King's X. Mudvayne and Dillinger Escape Plan are interesting musically but their singers leave me cold. Extol is incredible. The singing is tolerable. Suggestions for an aging fart?
