Carl Philipp Emanuel Bach, son of the great Johann Sebastian, didn't write much for organ. But there's such an idiosyncratically cheeky brio to what he did that it's well worth exploring. Ton Koopman is a player well attuned to the quirky turns that make CPE Bach's music especially appealing. And the attractiveness of his new recording of six organ sonatas is greatly heightened by the use of a gorgeous-sounding historic instrument that the composer knew and played. The Amalia Organ in Berlin, named after the organ-loving Princess Anna Amalia of Prussia, youngest sister of Frederick the Great, has recently been restored as closely as possible to its original condition. A near-perfect match of music, instrument and performer. challenge.nl
