MILTON BABBITT: PIANO WORKS. Robert Taub, piano. Harmonia Mundi 5160. This is piano music of high voltage, seeking constancy in change and finding no rest in its electrifying flight. Motion is active, vivid, and full of surprise. Nothing is redundant. No rhythm is allowed to wallow or stagnate. Taub performs in a most brilliant manner, the notes bursting from his piano with both control and aggression.
