Here's a list of organ composers whose major anniversaries we will celebrate in 2016:
Samuel Wesley (1766-1837) - 250
Johann Heinrich Buttstett (1666-1727) - 350
Johann Jacob Froberger (1616-1667) - 400
Matthias Weckmann (1616-1674) - 400
Daniel Pinkham (1923-2006) - 10
György Sándor Ligeti (1923-2006) - 10
Gaston (Gilbert) Litaize (1909-1991) - 25
Jean Langlais (1907-1991) - 25
Max Reger (1873-1916) - 100
Paul Siefert (1586-1666) - 350
Antonio (1510-1566) and Juan de Cabezón (1515?-1566) - 450
Froberger, Weckmann, Langlais, Reger, and Cabezon are big ones but I hope you will also play one or two pieces from the treasury of other lesser known composers to make sure their art gets attention it deserves.
HT to Cartayrade Alain who saw this drawing and added Maurice Durufle (1902-1986) - 30 years after his death.
Is there anyone else from the organ world on that list that I'm missing?
