Central Park (Listen to the Light) is a new album from Bluebrain – a site-specific work of music that responds to the listener’s location within the stretch of green of the same name in New York City and available exclusively as an iPhone and iPad app.

The second of their site-specific albums, this excellent video shows how the duo turn a landscape into a piece of music. Each piece of music is composed by them but ultimately the listener creates the end result depending on which way they decide to walk. Artists like Bluebrain open up all sorts of possibilities for other artists however whether the music is an album or an app is an interesting point raised in the film by legendary musician and Dischord Records founder, Ian MacKaye.

“To create the app, Bluebrain and contributing musicians composed a multitude of distinct musical segments, each of which corresponds with a designated geographic zone in the park,” explains its App Store listing. “As the user traverses these zones, Central Park (Listen to the Light) tracks their location via the iPhone‘s built-in GPS capabilities; the melody and rhythm of the music varies in accordance with the user’s path.”
