You ever pick up one of those mid-90s alterna-pop compilation CDs? This bill sounds like one of those comps, except instead of living in your hi-fi, it’s happening live and in person at O’Brien’s tonight.

HOWLO does a great Pixies impression, with a steady bass providing structure for spun-sugar psychedelic guitars and loud scratchy choruses. There’s something about WEATHER WEAPON that reminds me of Washing Machine-era Sonic Youth, distorted guitars with a spit-shine, and structures that are at once chaotic and self-assured. SHEPERDESS plays fuzzy pop behind a singer who moves from a whisper to a howl like it’s nothing, and then slaps a two-part harmony on top just for fun. RADIUM GIRLS are the odd screamy-hardcore band on the comp, but it just wouldn’t be the same without that one incongruous track.

Your CDs are long gone, but you can remember the glory of the comp disc in Allston tonight. –Josie Grove
