The opening of Mark Simpson’s new Cello Concerto is pure Hollywood. A fanfare in the low brass, an upwards rush and suddenly the screen floods with lush orchestral sound — as confident in its onward sweep as Star Wars or ‘Tara’s Theme’. Waiting, poised, in the middle of it all was the soloist Leonard Elschenbroich, for whom Simpson has said that he wanted to write a concerto that celebrated the cello’s ‘expressive and lyrical force’.
