Maybe the Flaming Lips decided to record a crazy, bass-heavy, guitar-free video for the Beatles psychedelic masterpiece ‘I Am the Walrus’ as a way to prepare for their upcoming New Year’s Eve concerts with Yoko Ono’s Plastic Ono Band in their hometown of Oklahoma City. More likely, they’re weirding out in the clip because, well, that’s what they do best.

Remember, this is the band that made their 1997 four-CD (meant to be played simultaneously) project ‘Zaireeka’ seem positively mainstream by recording the six-hour-long song, ’6 Hour Song (Found a Star on the Ground)’ and the 24-hour-long track, ’7 Skies H3′ earlier this year. Not that it has anything to do with the wigged out cover of ‘I Am the Walrus,’ but ’6 Hour Song’ features John Lennon and Yoko Ono’s son, Sean, reading the names of over 200 people who donated $100 to the project. Flaming Lips will release their final recording of the year, a 12-inch EP collaboration with Yoko Ono’s Plastic Ono Band, at the New Year’s shows.

Of course, the endless songs and upcoming EP weren’t all the madness Flaming Lips indulged in during 2011 — not by a long shot. Here’s a list of their bizarre offerings:

February: ‘Two Blobs F—ing’ — 12 YouTube clips meant to be played simultaneously
