Sunn O))) rules, saw them live at the ATP in Catskills in August last year. Quite heavy and seriously great transcendent stuff. Their Monoliths album is also great.
More transcendence:
Mountains - Air Museum
Nice I will have to check out that Mountains.
I saw My Bloody Valentine when they played in Chicago a couple years back. Incredible transcendent gut-rearranging stuff live. As is Sunn 0))) live (incredible stuff. A sonic experience). Another one I loved live was Pan Sonic, for similar visceral reasons.
Now I have moved on to the Salem "King Night" album. Celebrating the winter solstice a day or so late.
Not coincidentally, I am also demoing a potential subwoofer purchase (REL Storm III).
