Unique is probably the best word to describe the way the Flat Earth Society creates its musical recordings:
Flat earth society takes readings from the stylus of topographic radar, cuts them into vinyl and then plays them back with a stylus. Phonographic hills-and-dales grow into the Alps, Andes, Himalayas, Grand Canyon, Great Steppe, Great Rift Valley, Great Outback and the Lesser Antilles. Where Enrico Caruso and Nellie Melba once sang one hears the Baja Peninsula, Antarctic Peninsula, and the bathymetric pauses of the Red Sea and Baffin Bay. Peaks and valleys, spikes and wells, spires and troughs, aspirations and depressions, all have their gradations in mythical and actual landscapes.
