Boom Boom Room Reopens With Surprise Kanye West Performance (PHOTOS)

The space formerly known as the Boom Boom Room reopened Thursday night after closing for most of the summer.

While it's not entirely clear what's different at the Top of the Standard (it was rumored to be turning into a private members club, but that doesn't appear to be happening), Andre Balazs still brought out the A-list for his (somewhat) black-tie reopening.

Kanye West even got up on the bar and performed an impromptu surprise song.
