U2 tour stages. The most obvious examples would be the Trabant-lit, widescreen-adorned Zoo TV stage, the neon-filled Popmart stage with its gigantic LCD screen, and the current 360 "Claw" stage, but the relatively minimalistic heart-shaped Elevation stage deserves a mention. Their stage designer, Willie Williams, does this in many of his works.
Bono pointed out in a Rolling Stone piece that the 360 stage has been compared to that of David Bowie's Glass Spider Tour in 1987 — can you blame them? Bowie was one of the first rockers to use this trope, starting with 1974's Diamond Dogs Tour with its giant "Hunger City" set — so big and expensive that it eventually had to be dropped (complaints from the band and backup singers, who were all obscured by it for most of the show, probably didn't help). The 1990 Sound+Vision Tour substituted giant projections of Bowie and other performers for physical setpieces. Bowie averted this trope in other tours, such as the 1976 Isolar Tour that used only lighting to set scenes/moods... and even that was limited to white lights.
Snoop Dogg's video for "Beautiful" would be nothing but a stereotypical bootyshaking rap video if not for the breathtaking scenery of Rio De Janeiro. In fact, the last shot of the video is a panorama of the city with "Obrigado Brasil" ("Thank you Brazil") at the bottom of the screen.
Electronic music festivals have been trying to one-up each other in the stage department for years now. Bonus points go to ones with fairy tale-inspired atmospheres; EDC Las Vegas went from a generic bank of screens to a giant animatronic owl◊ in the course of a year.
