MUSIC—Where my Canadian tomboys at? Oh, look there they are… Tegan and Sara are back in town for the second time this fall, this time without the confetti wing-ding spectacular of headliner Katy Perry. The adorable twin-sister duo’s synth-pop is infectious, fun, and admired by a fervent fanbase of rabid indie popsters. Go; paint pastel squigglies on your face; dance. COURTNEY FERGUSON
