I went to Acid Mothers Temple on Friday here in Chicago. Excellent show! I wasn't sure what to expect...this was less on the "cosmic" / weird sounds side and more straightforward psych madness. Their playing was incredible and the various strengths of the members was on full display. If you can catch em on this tour I recommend it.
