Following is an update from the official Frank Zappa Facebook page:

"The first posthumous archival release from the '88 touring band focuses on the historic last show Frank Zappa ever played in the US, at the Nassau Coliseum in Uniondale, NY, with live concert material taken from that show plus additional performances from Providence, RI and Towson, MD, all newly remixed from the 48-track digital master tapes. 

It features the first official release of 'The Beatles Medley' along with over 25 unreleased performances and liner notes by FZ’s drummer, Chad Wackerman and Vaultmeister, Joe Travers. Available June 18th on stream / download; on 2-CD; or a 4-LP 180-gram black vinyl box set.
