Claudia Meza has a history with PICA. Her former band Explode into Colors performed at 2009’s TBA, and Meza curated the ongoing New Musics series. This year, she’s created an art tour based entirely on the properties of natural sound. Her Listening to Space: Sonic City PDX program functions as an audio tour of Portland, with Meza asking more than 30 musicians and artists to pick locations entirely for their ambient sonic possibilities. Freeway overpasses, open spaces, and the city’s buildings are all part of what you might find on the tour, which runs throughout TBA and is guided by QR codes and online maps. The tour concludes with an outside live concert from members of AU, Golden Retriever, and more, including Meza herself; location to be announced.
