Longtime Trey Anastasio associate Jen Hartswick will debut her new trio at a benefit concert this evening. Burlingtons Club Metronome will host the event, which will serve to raise funds for the Dale P. Camara Breast Cancer Foundation. This night of acoustic music also will offer sets from Rane and The Turkey Bullion Mafia. It is always possible that any of Harstwicks friends and family will join in the action as well, particularly since she is about to relocate to Chicago.
