Back in March, Best Fest hosted a special tribute concert to Brian Wilson, the aptly titled Brian Fest. The concert brought together the likes of Brandon Flowers, M. Ward, Best Coast’s Bethany Cosentino and more. Also included on the lineup were the Flaming Lips, who you can now see perform a psyched-out cover of the Beach Boys’ “Good Vibrations.” Watch above (via Flood Magazine).

The video acts as the first half of Brian Fest: A Night to Celebrate the Life and Music of Brian Wilson, a two-part documentary chronicling the concert. Wayne Coyne and company’s “Good Vibrations” cover is interspersed with interviews from Blondie Chaplin, Heart’s Ann Wilson, Local Natives -- among others.

“It’s hard to believe that a guy that young in that era was writing music that sophisticated that was called ‘pop,’” Flaming Lips’ Steven Drozd says in the video.

“He did [music] in a way that it slips past the normal listener,” Local Natives’ Ryan Hahn says in an interview, “‘cause it’s pop music, but then when you really dissect it, you’re looking at these chords and it’s, like, so intricate and complex.”

Hahn's bandmate, Kelcey Ayer, adds, “Beach Boys’ harmonies are still some of the most complicated harmonies in music.”

Wilson’s own bandmate, Al Jardine, seconded that sentiment, saying, “They’re great songs: brilliantly composed, and, simply, they’re written from another level. The synthesis of these voices -- when you think about it, the quality, it was pretty effortless, which is pretty unreal when you think about it.”

Flood’s documentary coincides with the forthcoming Brian Wilson biopic, Love and Mercy, which stars John Cusack and Paul Dano and lands in theaters this Friday (June 5).
