They're not strictly stoner rock, but whatever. Check out King Hobo.

Sleep, the Sword, Sun

If you want mellow, give Porcupine Tree a listen. They're probably one of the best progressive rock bands out there, man - and the tunes are great for "relaxation" time. I'd check out "Blackest Eyes," "Lazarus," and "Fear of a Blank Planet" and if you like it, go from there. Keep in mind though - the music is mellow as can be, but the lyrics get a little on the dark side from time to time.

has anyone mentioned 'orange goblin' yet? specifically their big black album? it's freaking awesome

Yea...this is the third time. I'm glad Orange Goblin starting to see some action, here. I love Frequencies, Time Traveling, and Thieving just as much as Big Black. Some other bands that also have a heavy groove and impeccably tasty time changes: Alabama Thunderpussy, Sixty Watt Shaman, and Black Label Society.

my bad, i was just too lazy to read through the thread :p:

I dont know what albums you have been listening to. Lazarus is off Deadwing which is a pretty heavy album. That song may be relaxing but the other nine or so are certainly not.. FOABP is also a pretty heavy album, with quite a bit heavily distorted riffs. And Blackest Eyes is FAR from relaxing, I mean when I play it through my speakers I feel the room vibrate.

For Orange Goblin fans: Check out Ravens Creed. It's Ben Ward's other band. I warn you though, they're NOT stoner rock. I saw 'em last summer, they kicked ass.

why are people naming songs when he said band.

That's true about Deadwing being a bit heavy - I meant the song on it's own.

As far as Blackest Eyes goes, I meant the vocals really - the music's hard, yeah - but their voices is what relaxes me. Then again, that's just a personal opinion.
