Echo in the Canyon is an unabashed celebration of the fecund music culture of Laurel Canyon, the mountainous burg in the Hollywood Hills that became a hotbed for hippies and innovative folk rockers in the mid-'60s. Jakob Dylan converses with scores of musicians who lived through that period, uncovering stories and anecdotes guaranteed to pique the interest of even the most casual rock fan. Director Andrew Slater mixes in archival footage featuring performances and interviews with Tom Petty, Brian Wilson, Ringo Starr, Michelle Phillips, Eric Clapton, Stephen Stills, David Crosby, Graham Nash, Roger McGuinn and Jackson Browne. If those names produce even the faintest shiver of excitement, then you are the audience for whom this film was made. ArcLight, 6360 Sunset Blvd., Hollywood; Fri.
