A new interactive composition allows listeners to create their own site-specific composition while walking around downtown Reykjavík, RÚV reports. Composed by brothers Úlfur and Halldór Eldjárn, Reykjavík GPS “is an ode to the centre of Reykjavík and its past, present and future. The music is connected to specific GPS coordinates in the city centre so you will hear it change as you walk through town.”
A member of the electro-rock band Apparat Organ Quartet, Úlfur has also composed for film, TV, and theater. Halldór is a composer and a member of the band Sykur, and also works as a computer programmer. This is the second interactive composition that the brothers have produced together: they debuted their Infinite String Quartet (still accessible here) during the 2015 Design March festival.
Reykjavík GPS became publicly available on June 4th as part of the Reykjavík Arts Festival. It only works in downtown Reykjavík, obviously, but once you’re there, all you need to experience the composition for yourself is “a smartphone, a good pair of headphones and good shoes.”
