As we approach the end of 2019, I've been thinking about our elders in the field of composition.
The oldest living classical composer I know of is Ned Rorem (b. 1923). Born in 1926 are Gyorgy Kurtag (Hungary), Friedrich Cerha (Austria), and Carlisle Floyd (USA). Canadian composer John Beckwith was born in 1927, while Canadian jazz and Third Stream composer Phil Nimmons was born in 1923, a bit before Rorem. Any others?
