Members of Furthur, the Disco Biscuits, Particle, Brothers Past and Bustle In Your Hedgerow will team up for a show at the Skydeck on the 99th floor of Chicago’s Willis Tower (formerly the Sears Tower) on Friday, November 22. JamBase is reporting that John Kadlecik, Allen Aucoin, Seve Molitz, Clay Parnell and Scott Metzger will be playing together as the “Skydeck Allstars.” The concert will be part of a series of “Top of the Tower” Thanksgiving shows.

Tickets to the show—which the promotors warn will “sell out fast”—are now on sale for $100. A small dinner will be served and free drinks will also be available.
