The Sundance Film Festival is still more than a week away, but the festival-film deal-making has already begun. Roadside Attractions has snapped up the U.S. theatrical rights to Jim Kohlberg’s THE MUSIC NEVER STOPPED, which will premiere on Sundance’s opening night, reports.

The film, based on a case-study essay by Dr. Oliver Sacks called “The Last Hippie,” stars J.K. Simmons (JUNO) and Cara Seymour (AN EDUCATION) as Henry and Helen, parents whose son, Gabriel, played by Lou Taylor Pucci, turns up at a hospital, 20 years after running away from home as a teen, with a benign brain tumor that has damaged his memory.  Seeking a way to reconnect with Gabriel, Henry enlists the help of a music therapist, played by Julia Ormand, and together they discover that the rock music of Gabriel’s past – The Grateful Dead, Bob Dylan, The Rolling Stones – may be his ticket back to the present.

“We were really moved by such a soulful, true story of a father and son changing their lives through their love of music,” Roadside co-president Howard Cohen said in a statement. “And you can’t beat The Grateful Dead, Bob Dylan, Beatles, Rolling Stones, Buffalo Springfield and Crosby, Stills & Nash music in this film.”
