Jay has a piece by Bach, and one of his best. He has another piece once attributed to Bach. And he has a third piece that may or not be—by the master, that is. In any case, wonderful music, and a highly interesting program.Bach?-Stokowski, Toccata and Fugue in D minor, BWV 565Stölzel (formerly attributed to Bach), “Bist du bei mir”Bach, Toccata and Fugue in D minor, BWV 538
