Conductor Markus Stenz makes a welcome return to the Barbican for this all-German programme, which takes in Beethoven’s revolutionary Fifth Symphony and Schumann’s graceful piano concerto, to be performed by Honens International Piano Competition winner, Hong Xu. Frenesia was written by Detlev Glanert as a tribute to Richard Strauss’s 150th anniversary, taking inspiration from the tremendous upsurge of kinetic energy at the start of Ein Heldenleben.
