TERRY GROSS, HOST:
This is FRESH AIR. Early in his career, clarinetist Andy Biskin worked as an assistant to the folklorist Alan Lomax. Biskin's new album features new settings of songs drawn from Lomax's massive collection "The Folk Songs Of North America." Jazz critic Kevin Whitehead says Biskin's album exposes a few layers of music history.
