Urban Songline created from a re-staging of Alvin Lucier' s Vespers. Transformed sounds created by the blindfolded volunteer-audience in the auditorium of the Stedelijk Museum in Amsterdam using SONDOL' s (Sonar Dolphin echolocation devices) creating an audible version of the space.
Volunteer audience members are blindfolded and asked to navigate and map the space based on echolocation. As if they were bats or dolphins they now have to hear their way through the space and form a mental image of the landscape based on the clicking echo's in the auditorium.
The recorded mapping of the auditorium serves as the input for the Urban Songline that is created from that sound profile. This music becomes a permanent translation of its shape, a tonal transcription that will allow anyone to hear the Auditorium as apposed to occupy or observe this space.
