Berkeley Symphony and their music director, Joana Carneiro deeply engage contemporary symphonic music in all its diversity. The amazing piano concerto of Gyögy Ligeti (1923-2006) still challenges performers and audience alike.

Then you can reflect on how different both of them are from Robert Schumann’s Symphony No. 2. The dynamic Israeli pianist Shai Wosner solos in the Ligeti.
