The Tech After Hours party is quietly becoming the coolest party in town. Booze, music, dancing, science exhibits-what's not to like? This time around, Casp3R-who hosts RetoXx, the underground electronic and hip-hop night at Johnny V's-will be providing the tunes. Star Trek is this month's theme. Casp3R plans to enhance his already cutting-edge electronic mix with some space-themed tracks and maybe even don a Star Trek Enterprise outfit (or at the very least, a NASA jumpsuit). After his appearance at the Tech, he goes back to RetoXx every Monday (which has two stages now), plus he opens for rapper Locksmith at the Agenda on May 10, and rappers Qwel & Maker at Johnny V's on May 27.
