Two hundred and thirty years after Bach, Górecki wrote a harpsichord concerto in the same key, using it ‘as a very rhythmic and extremely stealthy instrument’. John Adams, a leading figure of the American minimalist movement, composed Shaker Loops in 1978: ‘This masterpiece takes on a special interest because we play on instruments with gut strings. That gives the music a very special texture.’ Bach’s Passacaglia (‘a single musical theme heard forty-one times’) and Jehan Alain’s Litanies complete this programme, which brings together the Bestion brothers, with Louis-Noël Bestion de Camboulas as soloist in the concertos.
