One visible feature of our band was David Rosenboom's percussion rack. The usual jazz or rock and roll drummer gets along with a bass drum, snare, tom-tom, ride cymbal, and high hat, and sometimes one or two extras such as a second tom-tom or cymbal, and maybe a cowbell or some such novelty device.

When Dave appeared on stage surrounded not only by his large drum kit, but also by his home-made rack of bells, triangles, and other supplementary percussion, it made a striking visual impact.

As composers of new music, David and I were both intimately familiar with the then-current trend among composers to write for a large battery of percussion instruments. I had written two pieces myself that required enormous arrays of instruments (close to fifty of them in each), and David wrote at least one that I remember.
