"Heavy" Rock

Ive never heard of either of those bands, but if ypu want some life affirming rock n roll, check out Clutch. Classic band.

If you want pissed off rock, look no further than Unsane.

Probably not what youre looking for but both bands bring the rock
 
I'm big on stoner rock... which is fairly heavy and groovy as fuck.

Kyuss
Queens of the Stone Age
Witch
Clutch (already recc'd)
Graveyard
Orange Goblin
Nebula
Spiritual Beggars
Alabama Thunderpussy
The Atomic Bitchwax
etc.
 
Cable's "Skyhorse Jams" would fit nicely on that list

Another classic band would be Helmet. Hear Strap It On, Meantime, and Betty or die ordinary
 
I also support the Clutch rec and also put ASG - Win Us Over out there too
