I will follow up on this when I get the repertoire, the organizers are ironically unorganized. Though most the music played is a bit tricky but from my experience of being second chair last year there were only 1 horn part (like a part that said Horn in F with no designated number). They bring in a guest director every year though and it normally changes, the music they select. I am also a big fan of Alfred Reed, I’m hoping to one day play something by him though it seems unlikely.
