The Purcell Quartet - two violins, cello and continuo, augmented by two violas, recorders, oboe, bassoon, and trumpet - reflect the meagre forces available to Bach. The four solo singers combine in a one-to-a-part chorus… With no designated 'conductor', this is chamber music, warmed by the acoustic environment of a London church. The resulting clarity is delightful, more subtle that the similarly scaled Ricercar Consort (Mirare).

This is a well chosen programme, the sound recording is beautiful, and it is an effective advocacy of the one-per-part method.
