Query: Rock On!

I found this little gem while surfing amazon.com. Being a fan of Monster Magnet, Kyuss, Nebula, TAB, Fu etc, I decided to give this a shot - and it doesn't disappoint. Great riffs, blazing solos, and of course some awesome psychadelic stuff to boot. This is everything a stoner supergroup should be. If you are into the genre, pick this one up - you won't be sorry.
