KeyBank Pavilion (originally Coca-Cola Star Lake Amphitheater) is an outdoor amphitheater in Burgettstown, Pennsylvania, United States, 25 miles west of Pittsburgh. The venue holds approximately 23,000 fans: 7,100 in a reserved-seating, open-air pavilion and an additional 16,000 on a general-admission lawn. It is owned and operated by Live Nation.
The venue opened as Coca-Cola Star Lake Amphitheater and hosted its first national act, Billy Joel, on June 17, 1990. A second show was added on June 18, 1990 due to the record-breaking response. Since then, it has hosted many other "big-name" concerts. In 2000, the name of the venue was changed to the Post-Gazette Pavilion after the Pittsburgh Post-Gazette bought the naming rights. In February 2010, the publication announced it had not renewed its contract for naming rights to the facility, leading to First Niagara Bank to snatch up the naming rights. The facility was renamed again in 2016 after KeyCorp finished its acquisition of First Niagara.
Grateful Dead played the venue twice (June 22 and 23, 1992).
Phish recorded their show on July 29, 2003, at the venue, later releasing it as a live album entitled Live Phish 07.29.03. They subsequently performed a sold-out show on June 18, 2009, and again on June 23, 2012. All told, Phish have performed 7 shows at the venue the first in 1997 and the most recent in 2012. 
Kings of Leon were scheduled to perform during their Come Around Sundown World Tour on September 7, 2010, with The Whigs and The Black Keys as their opening acts, but the show was cancelled, due to scheduling conflicts.
The amphitheater has also played host to music festivals, including All That! Music and More Festival, Crüe Fest, Crüe Fest 2, Family Values Tour, Farm Aid, H.O.R.D.E. Festival, Honda Civic Tour, Identity Festival, Lilith Fair, Lollapalooza, Mayhem Festival, Ozzfest, Projekt Revolution, Uproar Festival, and Vans Warped Tour.
