Hold tight, as Vassily Sinaisky and the BBC Philharmonic plunge into a world of angels, demons, and fiery visions. This is Vaughan Williams’s Job, and it is as sensational as it sounds. First, Sinaisky shares two rarities from his native Russia: Lyadov’s jewel-like Folk Songs, and Prokofiev’s powerful Sinfonia Concertante. Leonard Elschenbroich’s reputation as a cellist who will push the instrument to its limits makes him the perfect soloist for this powerful piece, originally written for the great Mstislav Rostropovich.
