LIVE - From St. David's Hall in Cardiff. Presented by Catherine Bott. The BBC National Orchestra of Wales and the BBC National Chorus of Wales and soloists, under Thierry Fischer, with a poignant programme of music left unfinished by their composers: first, the Adagio from Mahler's Symphony No. 10 and then, after the interval, Mozart's Requiem, mysteriously commissioned - legend has it - by a masked stranger. MOZART - Requiem Mass in D minor, K. 626 Lucy Crowe, soprano Pamela Helen Stephen, mezzo-soprano James Gilchrist, tenor Peter Rose, bass BBC National Chorus of Wales BBC National Orchestra of Wales Thierry Fischer, conductor.
