Clutch is fucking awesome. My wife (who hates basically every band I've ever shown her, minus a few songs here and there from Corrosion of Conformity and Keith Caputo) even digs on them. I go through phases with Clutch, where either I love them or I'm simply OBSESSED with them. Only a handful of bands (and I truly mean a handful) can go through a musical evolution as they have and not get any backlash. None. If anything, they've earned themselves MORE fans.
Right now, I'm jamming on the 2LP 180g, six panel, megafuckingawesome Strange Cousins From The West vinyl that I picked up on my birthday, complete with new sequencing and two bonus tracks ("Metroliner Special" and an extended version of "50,000 Unstoppable Watts". It sounds epic. Mostly because it is.
My favorite song off Strange Cousins, "Abraham Lincoln". Live in England. Awesome.
