Love it or hate it — and it's nigh impossible to be neutral about the place — the Proletariat has something other Houston nightlife outposts wish they did: an honest-to-goodness scene, and quite a scene at that. In five years, the modest building near Richmond and Montrose has become perhaps the premier place for local musicians, DJs and artists of a certain stripe — think KTRU — to exhibit their works and exchange ideas, as well as get an eye-popping display of fashion coups and crimes among the club's youthful clientele (especially Thursdays at Rockbox). Even when it proves less than profitable, Proletariat's Houston-first attitude deserves to be celebrated right alongside the club's fifth-anniversary Saturday night. Like a real trooper, the club is even donating part of Saturday's take to like-minded local Web site the Skyline Network, who in turn are giving away some spiffy T-shirts listing everyone who's anyone in Houston music. That of course includes headliners Spain Colored Orange, premiering several songs from January's Sneaky Like a Villain, the full-length follow-up to their award-winning Hopelessly Incapable of Standing in the Way EP. Local pop standouts Paris Falls contribute some pleasing tunes from this summer's Vol. 1 and forthcoming Vol. 2, and then there's electro-goth crooner Wicked Poseur and "Misfit of R&B" You (genious) getting crazy on the solo tip, and turntable madness from DJs Witnes, Paramour and Melodic. Other goodies include free pizza and Red Bull, a keg of super-cheap beer and a few other things the club wants to keep under its hat until Saturday.
