Beastie Boys played a triumphant hour and a half set at Bonnaroo this weekend, but the biggest news was that Nas jumped onstage half way through the Beasties set to perform a song (it is tentatively titled "Let it Out) allegedly from the upcoming Beasties album, Hot Sauce Committee. A brief minute of the performance is above, and while it is very short, there's something so soothing about the Beasties and Nasty Nas getting together on a track. Hopefully they inspire each other to bring it back to 1994.

Hot Sauce Committee is due out sometime later this year. [via NahRight]
