The show was privately held in Electric Ballroom for Warner Bros Records executives. The band's manager and venue staff were likely in attendance as well.
While the exact date of the show is unknown, it probably happened sometime around late 1996, because on the recording Chester mentions the band is working on their new album with a tentative release date set for January. As we know, the band started pre-production for the album on December 3rd, 1996.
