Red Rocks Amphitheatre is an open-air amphitheatre in the western United States near Morrison, Colorado, approximately ten miles (16 km) southwest of Denver, which owns and operates it. In addition to several other large sandstone formations nearby, the venue is best recognized by its two massive monoliths, named "Ship Rock" and "Creation Rock", as well as the smaller "Stage Rock", which together flank its 9,525 capacity seating area and naturally form the amphitheater. While the venue is primarily known for hosting concerts and music festivals, other events of various types and sizes are held throughout the year.

U2 are an Irish rock band formed in Dublin in 1976. The group consists of Bono, the Edge, Adam Clayton, and Larry Mullen Jr.. Initially rooted in post-punk, U2's musical style has evolved throughout their career, yet has maintained an anthemic quality built on Bono's expressive vocals and the Edge's chiming, effects-based guitar sounds. Bono's lyrics, often embellished with spiritual imagery, focus on personal and sociopolitical themes. Popular for their live performances, the group have staged several elaborate tours over their career.
