The thirty-fifth classical recording: Aaron Copland - Rodeo
Looking at some sources, this is described as Broadway influenced - and indeed the ballet is abundant and loud in a way most aren't. It's, indeed, a play in the form of a ballet, and the two styles are an interesting mix - a traditional instrumentation with what feels like a more modern score (by the standards of the 1940s, of course. Can't go too far). There's also an old west influence, about a cowgirl trying to impress the cowboys. It's an unexpected mix, but it works - it's special and more than you might expect from a ballet at first.
