I somewhat agree with you guys, I could probably never hear Devilution and Rumors again and be happy. But I can't see them ever playing more than 75 minutes.
And of the songs listed, I've heard them play all of those (except the new ones) at some point.
4/11 Fear FestEvil w/ High on Fire
4/17 Electric Fucking Wizard
4/28 Mastodong/Clutch/Big Biz
