All-night Balkan Dance Party. Let that combination of words sink in for a second. All-Night Balkan Dance Party. Maybe that sounds more quirky than exciting, but trust us, it’s the latter. This glorious event is happening tonight at the Underground Arts as the wild West Philadelphia Orchestra plays three sets in celebration of the release of their new CD Live at Tritone. Don’t let their name fool you; though “West Philadelphia Orchestra” suggests suits, padded seating, and monocles, the WPO are far from stuffy. They’re an energetic ruckus, a collective of classical musicians playing Eastern European grooves so tight that after an evening of them, you might start waxing nostalgic about “the old country." Get to Underground Arts and jig, baby. Underground Arts, 340 N. 12th St., 9pm, $5 – Adam Downer
