I found a really cool CD today: Intermezzo, by The Modern Mandolin Quartet. The group is a string quartet, with mandolin-family instruments substituted for violin-types (i.e. two mandolins, a mandola and a mandocello) and they play arrangements of various classical pieces. Some are pretty much direct transcriptions of string quartets, but they also have arrangements of a Brahms intermezzo, Copland's Hoedown, a Bach fugue, and other stuff. And it all sounds awesome. I love it. Yay for mandolins!
