Fugue sur les Jeux d'Anches

Jean-Jacques Grunenwald (1911-1982) was a pupil of Dupré, and succeeded him at St. Sulpice in 1973. He composed a LOT of music, 19 works for organ (of which several have multiple movements). His music is not easy to play, but it rewards those who are willing to work for it - lots of accidentals, complex harmonies, etc. This is his wild Fugue from the Orgue et Liturgie volume #20 "La Fugue au XXe siècle"
