Video Sneak Peek: Avenged Sevenfold, 'Nightmare'

Here we have a sneak preview of Avenged Sevenfold's "Nightmare" video, directed by Wayne Isham. "Nightmare" is the title track from the hard-rocking California band's upcoming album of the same name.

If you're gonna make a video for a song about nightmares, you need a universally chilling environment, and the boys in Avenged have come up big here, setting the video in a creepy hospital, complete with crawling patients and terrifying attendants wearing Hazmat suits.

Check out the "Nightmare" sneak peek below. The full-length video premieres on Saturday, July 17 on MTV2. Avenged Sevenfold's Nightmare album drops on July 27.
