This is a benefit gig for LACMA, an art museum in Los Angeles. Beck is scheduled to perform at the museum's ART+FILM Gala fundraiser, hosted by Leonardo Dicaprio.
I do not know quite how long Beck performed, but I saw a lot of short clips on Instagram. He had most all of his Colors band there: Dave Grohl replaced Chris Coleman on drums, and Jake Sinclair was not there. Greg Kurstin was also with them, playing keys and guitar. From what I've seen, Grohl really powered up the songs too: vicious heavy versions of "E-Pro" and "Devils Haircut."
I did see a clip of them breaking into Led Zeppelin's "Immigrant Song," though am not sure if that was part of "Where It's At" or a cover they did on its own.
Also at one point, Beck had Annie Clark (St. Vincent) on stage and they attempted a cover of Blondie's "Rapture" (Annie was Deborah Harry, Beck did the rap). Clark was also on stage with them during 'Where It's At." (Again, I guess it's possible this was in the middle of 'Where It's At', I only saw a clip.)
