Mozart on Demand

Ah for the good old days when you could order up a piano concerto from the likes of Mozart (and at a cheap price by today's standards). Tonight we'll hear Mozart's concerto — not for one — but for three pianos, written in 1776 for Countess Antonia Lodron and her two daughters. Karl Engel, Till Engel and Leopold Hager do the honors; Hager conducts the Mozarteum-Orchester Salzburg.

Also tonight, celebrating the 49th birthday of Chinese composer Tan Dun: we'll hear selections from his 2000 score to the hit movie "Crouching Tiger, Hidden Dragon," featuring cellist Yo-Yo Ma.
