Chopin, Piano Concertos No. 1 and 2, performed by pianist Sa Chen and the Gulbenkian Orchestra Lisbon, Lawrence Foster, conductor (Pentatone Classics). Buffalo Philharmonic Orchestra followers will remember Sa Chen from a year ago. In October 2007, she joined the orchestra for an unusual work, a piano concerto by Clara Schumann. Chen looks about 12 on her album cover here, but she's 29. She is a promising pianist.
