This app by Phillip Lockwood-Holmes is part of the second HIDDEN DOOR, running 22-24 October 2010 at the Roxy Art House, Edinburgh. Music by Location plays a remix of the track Shifts by OVER THE WALL. As you move nearer to or further from the Roxy Art House the music will change in real time. If you are based outside Edinburgh, or just want to listen now, Music Now allows you to decide the type and length of remix you want. This remix will be dynamically created in a similar way to Music by Location.
