Music Composers Unite!
I was a composition major for a year (1982) at Illinois State University. The teacher was a guy named Roque Cordero, a Panamanian composer of some note amongst composers of note (I guess). His music was atonal and sounded to me like demented ragtime. http://en.wikipedia.org/wiki/Roque_Cordero
He wrote many fine pieces in traditional time signatures, but of course is best known for his compositions in unusual time signatures. I was listening to Rush Permanent Waves (their best, I think) today and realized that they too use all sorts of odd time signatures, and often change time multiple times throughout a piece. There are really only a small number of artists who work outside of the confines of 3/4 or 4/4 time.
