There is no string quartet that has ever been written that can compare length and diversity with Terry Riley's Salome Dances for Peace. Morton Feldman has written a longer one, but it is confined to his brilliant field of notational relationships and open tonal spaces. Riley's magnum opus, which dwarfs Beethoven's longest quartet by three, is a collection of so many different kinds of music, many of which had never been in string quartet form before and even more of which would – or should – never be rubbing up against one another in the same construct. Riley is a musical polymath, interested in music from all periods and cultures: there are trace elements of jazz and blues up against Indian classical music, North African Berber folk melodies, Native American ceremonial music, South American shamanistic power melodies – and many more. The reason they are brought together in this way is for the telling of an allegorical story. In Riley's re-examining Salome's place in history, he finds a way to redeem both her and the world through her talent.

With this disc, Miklós Spányi’s survey of the complete keyboard concertos of Carl Philipp Emanuel Bach, begun in 1995, reaches its conclusion. But over the years it has already been described as ‘a unique monument to one of the 18th century's most underrated composers’ (Gramophone) as well as ‘one of the most important and monumental recording projects of the century so far’ (MusicWeb International) and ‘an epoch-making achievement… in the history of recorded music’ (klassik-heute.de). Together, the 64 works – composed over a period of fifty-five years (1733-88) – form an endlessly fascinating picture of their composer’s various choices made in the course of a long career.
