Starting tonight at 9 PM, Lettuce’s killer set from Lockn’ Festival will be broadcast on Qello Concerts for free. Simultaneously, Let Us Play, the official Lettuce documentary, will be available with a subscription to Qello, the world’s largest collection of full-length concerts and music documentaries.

The 45-minute film, directed by Human Being Media and produced by Live for Live Music, merges footage from live sets, recording sessions, interviews, and candid scenes from the road. Filmed over a six-month period, the footage chronicles the mechanics of improvisation and the artistry behind making a funk record. Viewers will get an in-depth diagnosis of the band, who they are as artists, how they work together and use their ridiculous expertise to come up with some of the funkiest music around.
