Toccata and Fugue in D Minor; Sleepers Awake; Art of the Fugue , and Bach"s greatest preludes, trio sonatas, fantasies, passacaglias, chorale settings and more are all here, played on the Great Organ of St. Laurenskerk, Alkmaar, Netherlands and the Silbermann Organ in the Church of the St.-Pierre-le-Jeune, Strasburg.
