Click on this link to hear Herbert L. Clark and Leo Zimmerman play a trumpet and trombone duet from 1905 called "Alice, Where Art Thou?" http://cylinders.library.ucsb.edu/mp3s/2000/2946/cusb-cyl2946d.mp3 Pretty darn good fidelity for 101 years ago! Nice playing too. Bill Dinwiddie billdin at comcast.net
