Classic rock; instrumental jazz-rock-pop-funk-fusion; jazz ensembles and bands; concert bands and orchestras; classical music; and limited, but not much, smooth jazz.
Pre-D.C.I. and early D.C.I. Drum and Bugle Corps repertoires.
I avoid urban, rap, most heavy metal and techno, grunge, country, modern era pop (shudder), and almost all contemporary attempts to "make" music.
