People should take advantage of every opportunity to throw a party, whether they're commemorating one more year on the planet, moving into a new house, or coming to the hard-earned realization that people will only hang out with them when bribed with keg beer and giant tubs of Cheese Balls. Partying in celebration of their new website, Pure Grease. Grease is a graphic design + gear operation that started out printing edgy t-shirts for friends in bands; tomorrow night, they're throwing an all-out bash in celebration of their new online store, a fine excuse to rage FOR the machine. Taking over Beauty Bar, the bacchanalia will feature free eats from chicken & wafflery Salton Sweet, former clients like Trail of Dead, Not in the Face, and Eagle Claw playing an outdoor stage backdropped by a giant, lightning-bolted American flag, and, inside, ATX DJ royalty Prince Klassen performing his final set before moving to Japan, just like his rotund, home-run-hitting father, Cecil Klassen. Co-headlining the night will be three new shirts: Slick Rick Perry, depicting a smiling gov decked out in the foul-mouthed rapper's signature gold chains and eye-patch, and two attitude-driven white-lettering-on-black numbers proclaiming "YOU DON'T KNOW ME", and "LIBERTARIAN: SEX DRUGS & ROCK & ROLL", required dress at your next Tee party. Grease will also be slinging what's left of their band tees, with designs like a baroque warrior babe representing Trail of Dead, a dragon devouring an airplane for Pack of Wolves, and a North Face parodying print for Not in the Face bearing the subtitle "Climbing to New Lows", though in deference to Rob it should read "Climbing to New Lowes" -- now that was a party.
