For the Roskilde Festival, MorrowSound teamed up with Jes Vagnby Architecture and a group of lighting designers from Copenhagen International Theatre. For their site, they selected an open park in Ørestad, Tegnestuen, where the wind blows powerfully across the uninterrupted landscape.

The work was a set of large sail structures that interrupted the wind from different angles and was lit from below. Audiences could walk in and around the shifting design - making a kind of shadow theater. The sails alternately blocked the noise of the wind for moments of stillness, or resonated with it, creating an eerie singing in the open space.
