Opening the BBC Philharmonic’s Bridgewater Hall season, John Wilson conducts a sweeping selection of music from between the wars. We hear Dmitry Kabalevsky’s fizzing operatic overture, and Prokofiev’s fiery Third Piano Concerto - a showcase for virtuoso pianists and Alexander Gavrylyuk has made it a speciality. Contrast its confidence with William Walton’s searing, heartbroken First Symphony, written after the collapse of a ionate affair and now regarded as one of the greatest British symphonies ever written.
