I am the culprit who wrote the garbage concerto. It is a piece for percussion quintet and symphony orchestra. The solo instruments are made of recycled garbage (tin cans, glass jars, hub caps, plastic jars, a metal can maraca, blowing over bottles filled with water, etc.). It is beautifully recorded by BIS. The best price seems to be at www.cdnow.com. Enjoy! Jan Jarvlepp
