Hollywood Casino Amphitheatre (Maryland Heights, Missouri)

The Hollywood Casino Amphitheatre (originally Riverport Amphitheatre and formerly the UMB Bank Pavilion and Verizon Wireless Amphitheater) is an outdoor concert venue in Maryland Heights, Missouri, near St. Louis.

History
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, July 2, 1991, during a Guns N' Roses concert, during their Use Your Illusion Tour.

In 1998, the local promoter Contemporary Group, who built the amphitheater, was acquired by SFX. SFX corporate successor Live Nation Entertainment continues to own and operate the venue.

In 2002, UMB Bank acquired the naming rights to the venue for five years. Verizon Wireless then purchased the naming rights in November 2006.

Venue owner Live Nation announced December 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. Even with naming rights changes, many in the St. Louis area still call it by its original name "Riverport".
