Watch live streaming video from beastieboys at livestream.com
There have been a few posts recently here about the upcoming Beastie Boys album "Hot Sauce Committee Pt. 2" which is being released May 3rd and you can pre-order here. Leading up to the release the Beastie Boys put on a Live Stream video which you can re-watch above featuring a speaker right in the middle of Madison Square Garden streaming the album.
Makes perfect sense.
