The Verizon Wireless Amphitheater St. Louis (commonly known as Verizon Wireless Amphitheater and previously Riverport Amphitheater and UMB Bank Pavilion) is a 7,000-seat outdoor concert venue, with lawn seating for another 13,000, making it a 20,000 person capacity venue. It is located at 14141 Riverport Drive, Maryland Heights, Missouri, near St. Louis, one mile west of the I-270 and I-70 interchange, at I-70 and Earth City Expressway South (exit 231A).
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.This riot was the cause of the band's ban from St. Louis, disallowing them to play in the area.
In 1998, Contemporary Group, who built the ampitheater, was acquired by SFX. SFX corporate successor Live Nation Entertainment continues to own and operate the venue.
The amphitheatre has played host to music festivals, including The Vans Warped Tour, The Mayhem Festival, Farm Aid, Projekt Revolution, Lollapalooza, Ozzfest and Lilith Fair.
