Here is Johann Sebastian Bach in transfigured light: with organ chorale preludes, vocal cantata movements and orchestral sinfonias – 24 pieces in all – transcribed for trio and solo piano by Fred Thomas, and threaded into a compelling new sequence by Manfred Eicher. On Three Or One, Bach’s idiom is respectfully explored by three innovative players, a process Thomas describes as “quietly joyful,” and the trio pieces, primarily drawn from Bach’s Orgelbüchlein, acquire a fresh character in the hands of Kazakh violinist Aisha Orazbayeva and British cellist Lucy Railton, musicians more often associated with contemporary composition’s cutting edge.
