“ANDREW W.K. = PARTY” reads the man’s Twitter bio. Boldface those caps, turn the amps to 11, pop some amphetamines, and irrigate your colon, and you’ll know what Andrew W.K. feels like all the time. A supreme motivator, this classically trained pianist has harnessed his positivity into anthems of pop-metal bluster that make Slade seem sedate. The recent Gundam Rock found Andrew bombastically covering Japanese anime music, but tonight’s show will feature the man’s explosively wonderful 2002 debut, I Get Wet, played in its entirety.
