The film stars Lou Adler, Fiona Apple, the Beach Boys, Beck, Tom Petty, Jackson Browne, Buffalo Springfield, the Byrds, Jade Castrinos, Eric Clapton, David Crosby, Jakob Dylan, Norah Jones, and Michelle Phillips.

It was a moment (1965 to 1967) when bands came to L.A. to emulate the Beatles and Laurel Canyon emerged as a hotbed of creativity and collaboration for a new generation of musicians who would soon put an indelible stamp on the history of American popular music.

Echo in the Canyon contains candid conversations and performances with Brian Wilson (The Beach Boys), Michelle Phillips (The Mamas & the Papas), Stephen Stills (Buffalo Springfield), David Crosby (The Byrds), Roger McGuinn (The Byrds), their contemporaries Ringo Starr, Eric Clapton, Graham Nash and slightly younger followers Jackson Browne and Tom Petty (in his last film interview), as well as more recent musicians influenced by their music, such as Beck, Fiona Apple, Cat Power, Jade Castrinos, Regina Spektor and Norah Jones.

"[5] Brad Wheeler of The Globe and Mail wrote, "That's David Crosby's take on the seminal California folk-rock scene of 1965 to '67, an era explained lovingly and with due reverence in the hashish-scented documentary Echo in the Canyon.

"[6] In addition, the movie has been criticized for glaring omissions about the historical period, namely other rock music luminaries who resided in the area at that time, such as Jim Morrison of the Doors and the singer-songwriter Joni Mitchell.
