Windhand's Soma is incredible. It's a sort of mix of the drone guitar from Sunn O))) with Sleep's percussion (although neither comparison is completely accurate). Cassock, the second to last track, already had me completely wowed over the album but then came Boleskine, the 30-minute closing track. Insanely good. One of the better releases of this year, from any genre.
Pretty much why I'm going to the High on Fire show in December at the El Rey.
