BBC Singers at St Paul's Knightsbridge. Presented by Christopher Cook The BBC Singers have the largest and broadest repertoire of any professional choral group, and their programme at St Paul's shows their versatility, spanning four hundred years of the choral repertoire, beginning with William Byrd's Mass - one of the sacred masterpieces of the Tudor period, conducted by Chief Conductor David Hill. Then Principal Guest Conductor Bob Chilcott conducts three works composed by the Singers' Associate Composers over the last six years, plus a piece of his own - which requires audience participation! And to conclude the concert, David Hill directs three choral classics which were commissioned for and premiered by the BBC Singers in the 1940s. Tippett's The Weeping Babe and Britten's Shepherd's Carol are amongst the group's earliest commissions - composed for a programme called A Poet's Christmas which was broadcast in 1944. And Poulenc's monumental wartime cantata for unaccompanied voices, composed as a hymn to freedom in occupied France during the summer of 1943 was given its first performance a few months later by the BBC Singers in the Concert Hall of Broadcasting House. It is one of the most thrilling and powerful works in the entire choral repertoire.
