Born in 1939, Barbara Kolb is an American composer of challenging classical music. Case in point: The title track of this ancient 1992 CD serves up a nearly 20-minute helping of dissonant avant garde classical chamber orchestra music layered with quiet electronic drones via computer generated tape. Here and there, the listener encounters starts and stops; and abrupt, urgent, repetitive rhythms with a playful xylophone that frolicks around the sound field without a care in the world. Can you say, “Sustained dreamworld?” The second track, “Extremes,” ironically simplifies the proceedings with a sprightly flute and droning cello. Not too far along, both get all melodic on your ass, then seque out onto a dead end street full of odd, cantankerous riffs.
