I stole some recordings of virtuoso violinist Maja Cerar and went berserk with DSP fun:

the Majas: http://music.columbia.edu/~brad/music/mp3/Maja-Q.mp3 http://music.columbia.edu/~brad/music/mp3/Maja-L.mp3 http://music.columbia.edu/~brad/music/mp3/Maja-J.mp3 (each about 5 mins long)

commentary: http://music.columbia.edu/~brad/music/commentary/the_Majas.html

Much max/msp-ing involved, of course. :-)

Hope you enjoy them!

PS: I hope people don't mind when I post links to music here. I know it's (pun perhaps intended) "blowing your own horn", but I personally like when other people post what the sounds they're making. If this is really inappropriate, I'll stop.
