I'm wondering what kind of odd tempo markings you've come across, for me the most recent one I can put my hand to is Moderato Pesante. No idea other than the moderato part. What about your weird markings?
I love this piece!! Mvt 1 is my fav, but the entire piece is fun to listen toThe contemporary American composer Michael Daugherty (1954-) has a terrificly clever work called the "Metropolis Symphony ", which believe it or not, is a program symphony about Superman and the other characters from the comic strip !
One movement has a tempo marking called "faster than a speeding bullet ". I kid you not ! I'ts great fun, and uses all kinds of unusual instruments, such as a musical saw and police sirens etc, and tons of percussion.
I recently heard the Argo recording with David Zinman and the Baltimore symphony. It may not be easy to find, but check arkivmusic.com, the best place on the internet for hard-to-find classical CDs. They also have a terrific general selection, plus DVDs.
