TOD - Quite a few, but these stand out
- Discovering rock music I really liked in high school by checking Chicago II out from the city library.
- Discovering jazz at Interlochen through big band concerts. First Stan Kenton, then Duke Ellington, Woody Herman, and Count Basie in later years.
- Discovering Kurt Weill by, of all things, playing the suite from Der Silbersee in my college orchestra.
