At which Colorado venue did U2 film the 1983 concert movie Under the Blood Red Sky?

U2 filmed the 1983 concert movie Under the Blood Red Sky at Red Rocks Amphitheatre in Colorado. The venue's dramatic natural setting became central to the film's visual identity.

The concert took place on 5 June 1983 near Morrison, Colorado, during U2's War Tour. Rain and atmospheric lighting intensified the performance, especially during songs such as “Sunday Bloody Sunday” and “The Electric Co.”

The concert film was released in 1983 alongside the live album Under a Blood Red Sky. The album itself combined recordings from several War Tour performances, so not every track came from Red Rocks. That distinction is a common source of confusion.
