One of the perks of music journalism is that you get to write about some freakin’ sweet events. Tonight, that freaky sweetness is the reemergence of seminal Philly post-punkers Crash Course in Science at AUX (Vox Populi). The band has been around since 1979 (three years before a scientifically-apt woman blinded fellow new waver Thomas Dolby – guess he should’ve listened to these guys, eh? Anyone? Right, moving on…), playing an experimental type of New Wave that blended the genre’s affinity for quirk with performance art. Traditional instruments were eschewed for toy ones, drum sets for drum machines, and “Frankenstein”-style homemade noisemakers were added for good measure. Their first record, Signals from Pier Thirteen, is regarded as one of the major influences to industrial techno, and is a highly-regarded collectible for music fanatics. And they’re playing hometown show tonight. And other post-punk and fuzz-pop Philly acts like Psychic Teens and Hurry are opening as well as out-of-towners Normal Love and The Young Leaves. And it’s all ages. Pretty freakin’ sweet, right? AUX (Vox Populi), 319 N. 11th St. – 3rd Floor, 8pm, $8 – Adam Downer
