In May 2004, Mitsuko Uchida sat at a piano in front of a chamber-size version of the Chicago Symphony Orchestra and with dancing arms and generous facial expressions elicited refined, superbly balanced, and utterly captivating readings of Mozart's 13th and 19th concerti. Now this sensitive and intelligent musician returns for a program that includes Bach's glorious Brandenburg Concerto no. 5, also featuring CSO principal flutist Mathieu Dufour (who stole the show in a performance of the work at Ravinia last summer) and concertmaster Robert Chen. Also on the program are Mozart's delightful Serenade no. 11 in E-flat, K. 375, and the composer's most outwardly impassioned piano concerto, the D Minor, K. 466, which after its agitated introduction has the piano enter as an upwardly reaching single voice. The lovely middle movement is followed by an aggressive and stormy finale, which is among the composer's most Beethovenian in spirit.
