The new name for "Then & Now" with host Sarah Cahill. "Revolutions Per Minute" speaks to the musical revolutions of Beethoven, Stravinsky, and John Cage, among others, and evokes the 33 rpms many of us treasure, whether we're sentimentalists or audiophiles. "RPM" will feature more vinyl in regular broadcasts, and encourages listeners to bring their favorite classical records for broadcast and discussion (e-mail email@example.com). You'll still hear the musical juxtapositions of Hildegard von Bingen with Meredith Monk, and Josquin des Pres with Frederic Rzewski. Plus interviews with composers and musicians, local and internationally acclaimed, as well as previews of Bay Area concerts. Sundays from 8-10pm.
