Venue owner Live Nation announced Dec 17, 2014 that they had signed a multiyear agreement with Hollywood Casino in Maryland Heights, which is owned and operated by Penn National Gaming, to be the amphitheater's title sponsor. The length of the agreement was not disclosed.
The venue was built for approximately $12 million, and opened on June 14, 1991, with a performance by Steve Winwood.
Shortly after opening, the amphitheater became the site of the infamous Riverport Riot, sparked by Axl Rose, during a Guns N' Roses concert, during their Use Your Illusion Tour.
