Unlike most 2010s instro-metal, there's nothing "post" rock about this improvising Austin trio. They could be back on a 1969 mud-festival stage, blasting heavy Groundhogs or Santana fusion-psych boogie into the Apollo 11 zone while keeping it caked in soil, sweat and pipe residue. Cosmic Priestess kicks off with a Sabbath riff, then gets proggier and bluesier from there. Four jams stretch across 60 minutes, including 33 for Sun Ra's favorite planet. Solos stay non-boring; drive and groove maintain; the final cut funks out with wah-wahs and Kraut-rock zap guns. Then you exhale.
