Local quartet Church Girls celebrate the release of their self-titled debut EP tonight at MilkBoy Philly. Mariel Beaumont’s vocals vary from joy-filled to half-spoken downcast and world-weary. The instrumentation on the album captures a crisp steady fervent feel anchored by a tightly wound backend and electric guitar runs that are ready to spring loose. Multi-instrumentalist and audio engineer Jesse Gimbel, who contributed backing vocals on the release, dishes a rocking take on the singer-songwriter genre, incorporating lively licks into personal tales. Marc Neibauer’s tunnel-traveling, melodically peaceful tunes open this evening. MilkBoy Philly, 1100 Chestnut St., 8:30pm, $10, 21+ – Michael Colavita
