The opening chords of Beethoven’s ‘Eroica’ Symphony are like a jolt of electricity – and some would say that classical music is still reeling from the shockwaves. Forged in an age of revolution, this is a symphony on an uncompromising scale, delivered with a directness that never gets any less startling. In other words, it’s perfect for the LPO’s charismatic Principal Guest Conductor Karina Canellakis.
