Comet followed with its first Dallas concert in seven years, but on Sunday night, the group sounded like it had arrived at the Gypsy in a 1997 time machine. Their ultra-loud shoegazer style remained completely intact, and the band's booming drums, whispery vocals and soaring guitars made theirs a welcome reunion. The next act brought out a mixer, distortion pedals and a laptop, but it wasn't Tree Wave. Rather, it was John Lamonica. What the F? Last time I saw him, he was the reincarnation of Jeff Buckley with a full, mainstream-rock band, and yet, there he was, half-naked, singing and dancing to techno beats à la The Postal Service (which, I confirmed, is his new style). His voice is so gorgeous that he can get away with that switch even as a joke, but his sincerity quickly became apparent, and after a sensational sing-along acoustic number, he resumed the beats and whipped the crowd into a dancing frenzy. Not to be outdone in the tech department, Tree Wave closed the show with a vintage computer rig that pumped out lovely synth tunes and psychedelic video. Of particular note was "Dodge Em," in which programmer Paul Slocum controlled the audio by playing a classic video game without dying once. Singer Lauren Gray called it a perfect game, and with cheers and howls, the crowd agreed.
