In the 50th-anniversary year of the Royal Northern College of Music, former student Sir Stephen Hough plays Rachmaninov’s First Piano Concerto – a work full of Romantic passion and ‘youthful freshness’, written while the composer was still a teenage student. Hough is joined onstage by the Manchester-based BBC Philharmonic and conductor Mark Wigglesworth, who also perform Mahler’s First Symphony and a new commission from rising-star composer Grace-Evangeline Mason.
