Edelweiss, the high school-aged quartet from Pennsylvania, is bringing their indie pop sound to Arlene’s Grocery on Sept. 27. The indie band is out to show the world that age is merely a number, especially when it comes to music. Their self-released debut EP, Pre-Columbians, is going to throw the band into the ranks of some of their heroes, such as Minus The Bear and Foals. The show is 21+ and admission is $8.
