Mary Lattimore might be Philadelphia’s greatest musical export. And that’s saying something, considering the wealth of internationally revered musical talent the city has bred in recent years. A classically trained harpist, Lattimore’s been playing her instrument for more than 20 years. She’s toured the world both as a solo performer and with her many musical collaborators, including Kurt Vile, Thurston Moore, Sharon Van Etten, Steve Gunn, Jarvis Cocker, Meg Baird, and her most frequent collaborator, musician/producer Jeff Zeigler. The dense, gorgeous music she makes isn’t defined by the mastery of the harp so much as by her experimentation with it.
