The Black Angels bliss out at the Bottleneck on Saturday night

It’s easy to imagine the Black Angels recording in a hot, windowless Texas basement in midsummer. The Austin band’s languid, throbbing garage-psych swelters, all claustrophobic, with wall-to-wall guitars that buzz and snake like severed high-tension power lines. The Velvet Underground inspired the Angels’ sound as well as the band’s name (“Black Angel’s Death Song”), but the gloomy narcotic hum that swirls and descends through the music does more than pay homage.
