Bay Area pianist, composer, fiddler, singer Barbara Higbie talks to Derk about her cello-centric show at Yoshi's Oakland next Thursday night with Joan Jeanrenaud and Jami Sieber, with, as they say, "musical examples." Plus, a tribute to the late Levon Helm--drummer, singer, mandolinist, guitarist, with The Band and in an illustrious solo career--who died today at the age of 71.
