It’s a Friday night in Austin, Texas and The Black Angels are wowing a huge crowd with a reverb-heavy set at Cedar St. Courtyard during SXSW 2011. The lights are turned down to a low red glow and people dance as if they’ve been possessed by some sort of rock n’ roll demon. Lead singer Alex Maas appears to be in a meditative trance as he belts out lyrics to songs from the group’s most recent release, Phosphene Dream.
