Washington, D.C.-based band Bluebrain’s new album dropped yesterday, Friday, May 29, 2011, but not in the way one might think. It is available on iTunes, but not in MP3 form — rather as a location-aware app that only works within the stretch of park in downtown D.C. called the Mall.

“The music changes and evolves based on your chosen path within the park,” says Ryan Holladay, one half of the band. (His brother, Hays, makes up the other half of the outfit.) “To do this, the app uses the phone’s built-in GPS capabilities.” The app features a map of the Mall that shows what locations are tagged with sound.

The album, titled The National Mall, contains about three hours of music that the brothers composed while traipsing around the area. “It was certainly the most amount of exercise I’ve ever gotten while making an album,” Holladay says.

The disc will not be available for standard download as a musical piece, since it will only work when one is standing in the Mall.
