Baroque music specialist Dr Simon Heighes chooses his favourite version of Bach's Motets. These technically challenging works contain some of Bach's very best music and can be thrilling in performance by a top-notch group of singers. They're also the only of Bach's vocal works that stayed in the repertoire without interruption between his death in 1750 and the 19th-century Bach Revival. Recordings reviewed include performances by The Sixteen and Voces8 & The Senesino Players. Presented by Andrew McGregor.
