“Piano Concerto No. 4 in G Major, Op. 58” is one of Ludwig van Beethoven’s masterpieces, helping to cement his place in music history. “We have to expect the unexpected in this concerto,” said musicologist Mark Rohr, “because Beethoven looks at the form and says, ‘Why, anyone could do that. I believe I’ll do something a bit more fun.’” Pianist Andrew Hsu will be performing the concerto with guest Conductor Courtney Lewis. The program also includes Robert Schumann’s “Symphony No. 2 in C Major, Op. 61” and the overture to the opera “Oberon” by Carl Maria von Weber.
