Joe Westerlund is a drummer, composer, and improviser who works within a variety of musical outlets. Ongoing and intermittent affiliations include Mandolin Orange, Califone, William Tyler, Sylvan Esso, Bon Iver, Arnold Dreyblatt, Eugene Chadbourne and Gayngs, among a diverse cast of interpreters of sound and form.  While studying with avant-garde jazz luminary, Milford Graves, Joe began collaborating with choreographers, and has since composed music for modern dance and film. He has worked closely with dance faculty at UCLA, Bennington College, NCSU and Meredith College; and regularly accompanies Prana Vinyasa yoga classes with his wife, Carson Efird.  In 2014, Joe released his first recording as a solo artist under the alias Grandma Sparrow, in collaboration with Spacebomb Productions.  Last year, after relocating from Los Angeles, he released Mojave Interlude on Northern Spy Records, a piece built largely from electronically manipulated percussion.  Joe now continues his work as a session/touring musician out of Durham, North Carolina.
