The comparatively small, but — in musical terms — hugely important geographical area called Laurel Canyon in L.A. is investigated in the documentary, Echo in the Canyon. Directed by Andrew Slater, the film details how the Byrds, the Beach Boys, Buffalo Springfield, and the Mamas and the Papas birthed the still influential “California sound” in the mid-’60s. Directed by Andrew Slater, the film features contributions from Brian Wilson, Michelle Phillips, Ringo Starr, Eric Clapton, Stephen Stills, Roger McGuinn, Graham Nash, David Crosby, Jackson Browne, and the late Tom Petty in his final filmed interview.

“The best test of songwriting is that it transcends its moment in time and there is no doubt that the songs we explore in this film are as powerful today as they were in 1965,” said executive producer Jakob Dylan in a statement.

Echo in the Canyon opens in Los Angeles on May 24 at Arclight’s Cinerama Dome and the Landmark followed by a New York opening at the Angelika and the Landmark at 57 West on May 31. Both openings will feature performances by musicians from the film all weekend with a national rollout and a soundtrack on BMG Music following in June.
