Brainbug is a symphonic electronic trance music project based in Venice, created by Italian producer Alberto Bertapelle. Brainbug became widely known after the release of his first single, Nightmare (1996), because of the unique blending of string instruments, haunting atmospheres and house beats.

Nightmare appears in several movies, (Human Traffic, Playing by Heart, and A Night at the Roxbury), and is currently played during the second half kick-off at Leeds United home games at Elland Road as well as being the entrance music for the 2013 Elite League Nottingham Panthers Ice Hockey team. The music video was directed by Tim Claxton and was inspired by 1950s science fiction films, and the films of Ed Wood.
