20th Century Innovations The repertoire for this performance featured several instruments for which there were multiple performers, including flute, bass clarinet, French horn, and violin. For those works for which the instrumentation called for only a single one of those instruments, no performer assignments have been made on those instruments, since the printed concert program only provides an overall list of performers, not a list for each individual work.
