Flotation Device bids farewell to Éliane Radigue with a look at her audacious and beautiful music built from complex, slowly-transforming drones. Our survey of her electronic landmarks of the 20th century and her acoustic compositions of the 21st emphasizes the importance of tantric Buddhism in her works, which often bear Tibetan titles and remind many listeners of the experience of deep meditation. Also on the docket are signature compositions by Murail and Stockhausen celebrating their 50th anniversaries. Plus Craig Taborn unveils a new trio, Gustavo Cortiñas debuts a new quartet and Fred Frith’s Gravity Band gets its first album twelve years after its only tour. A John Oswald plunderphonics etude for pianist Marc-André Hamelin rounds out the program. Creative and improvised music from the Northwest and around the world with host Michael Schell.
