Despite this fancy smartphone integration, Bluebrain stresses that this is still an album, not a toy or augmented reality application. The experience is strictly location specific, no user input necessary, or available. Want to hear a new melody or arrangement? Walk to a different monument. The project's location-specific nature means that fans outside of the DC area are out of luck for now. The band says two more GPS-powered albums are on the way -- one designed for Brooklyn's Prospect Park, and another spanning the entire length of California's Highway 1. Music, measured in miles -- neat, but Hwy. 1 manages just fine on its own, wouldn't you say?
