For a band that wasn’t even supposed to exist, Scars On 45 have caused an uproar in a short amount of time. They were recently featured on tour with Matt Nathanson and even played select tour dates with Jack’s Mannequin. Even their music from their latest EP, Hearts On Fire has made it into Grey’s Anatomy Original Soundtrack Volume 4. The quintet will be performing at the Rockwood Music Hall on Nov. 21 with Chelsea Lee. Doors are at 6:30 p.m., and tickets are $12. The show is 21+ with a one drink minimum.
