1This week on The Marketplace of Ideas, Colin Marshall talks to Portland-based electro-acoustic musician and old technology enthusiast Ethan Rose. Rose’s newest album, Oaks, is assembled entirely from sounds recorded on a vintage 1920s Wurlitzer organ he stumbled upon at the skating rink of Portland’s historic, iconic Oaks Park. During the composition process, Rose came to know intimately the inner workings of this elaborate sound machine, working alongside its official maintainer, looking for ways to generate sounds like the organ had never made before and using computers to process them in ways its creators never would have expected.
