The first movement of a concerto for Cello and orchestra I wrote a few months ago based on some Appalachian folk songs.
Here's a little list of what's happening in the piece, for whoever's interested:
0:00 Introduction
0:33 First tune, "Arise, arise, you slumbering sleeper" played in the orchestra, then picked up by the cello
1:51 Second tune, "East Virginia"
3:18 Cadenza (solo) for the cello
4:13 Reprise of the introduction
4:50 Second Cadenza for the cello
5:28 Reprise of the first tune
6:04 Reprise of the second tune
6:30 Coda
