Flotation Device celebrates the 100th birthday of the indefatigable Franco-American composer Betsy Jolas, and the 50th anniversaries of Anthony Braxton’s Duets 1976, Wadada Leo Smith’s Song of Humanity and The Residents’ Six Things to a Cycle—three recordings whose echoes we’ll discern in new offerings by Mat Maneri, Sylvie Courvoisier, Patricia Brennan and Metal Preyers. We’ll take our first look at Jin Hi Kim’s new nine-CD career retrospective and our second look at BIS Records’ new Anders Hillborg anthology, while Philip Glass’s latest album makes an interesting contrast to his landmark opera Einstein on the Beach whose golden anniversary we celebrated last week. Cassandra Miller gets her own 50th birthday shoutout, while Stuart McLeod and Steven Eric Scribner demonstrate two facets of the Pacific Northwest’s formidable electroacoustic scene. Creative and improvised music with host Michael Schell, from 91.3 KBCS-FM Bellevue/Seattle/Tacoma.
