When Swearin’ hits the stage at The Boot & Saddle, its members bring a road-tested, garage-punk vibe. Harvesting emotional attitudes while hovering the threshold of a polished performance yet retaining honest, appealing grit, their songs spring forward meshing the interplay of male and female vocals, demonstrating a pace that at times is easy to latch onto, while conversely, at others, pushes the pace ratcheting up the intensity gauge as the clean, snappy percussion takes on adrenalized smashes with bass hitting like a sledgehammer and guitars jaggedly fuzzing out. The steady charge of youthful Massachusetts garage-pop, all-female quartet Potty Mouth reinforce the bill which is also supported by relative newcomer, West Philly trio Urine Culture. The Boot & Saddle, 1131 S. Broad St., 8pm, $12, 21+ – Michael Colavita
