I play the French horn and the piano (though I’m pretty pants at the piano).
I played a lot of film music, “songs from the shows” stuff, arrangements of pop songs, jazz standards and also some “modern” music of the sort that doesn’t have much of a tune, at least at first listen.
At University I did a lot more modern stuff, sometimes with bands, sometimes with orchestras. I often got to talk to the composers which I found fun and I have played in and conducted some world premiers of pieces.
These days it’s mainly orchestral stuff by dead composers that I do as it tends to be too expensive to hire the music written by living composers.
Looking at my CD collection now the people I have the most CDs of are David Bowie (good return to form with the latest album), Pink Floyd and Philip Glass. Philip Glass is interesting – he has written music about science before, for example a piece called “The photographer” all about photographs of horses and an opera called “Einstein on the beach”
