John Moose is a Swedish folk band that has chosen to pre-release their debut album and make it publicly available for free! But here’s the catch: you can only listen to it when you are in the woods. After downloading the John Moose app, listeners have the full album available to them on their smartphones. However, since the album will only play once you are in the forest, the next step is to go out into the woods in order to press play.
The app works by using Google Maps to identify areas that are forests (those that are shaded a specific green on the mapping system). Then, the coordinates are sent from your phone and that is what allows you to access the album. By releasing an album in such a way the band is offering listeners a unique and multi-sensory experience of their music whilst also encouraging people to go out and spend time in nature.
