Grizzly Bear teamed up with their old friend Victoria Legrand from Beach House for a performance on Conan O’Brien’s show last night (Oct. 12). The band performed “Two Weeks” from Veckatimest, and Legrand provided some heavily reverbed accompaniment.

Sadly, Jay-Z and Beyonce weren’t in the audience this time around (surely that collaboration is just a matter of time?). But the band delivered a note-perfect version of the song, and then destroyed their instruments in a fit of Cobain-esque rage, with Ed Droste ripping off all his clothes and bellowing like a wildebeest.*

*That last part might not be true.
