These performances were made at various locations. Many were made during peformances sponsored by Columbia Concerts. They are unedited except for timing between movements. There are somewhat noisy, especially 118b, but in our opinion the performances are outstanding. The compositions by Harsanyi and Persechetti in 118a are contemporary. The latter composition is for flute and harp. In 118b Blavet and Marcello are Baroque. Felciano is for alto flute and tape. It, Hindemith and Milhaud are contemporary.
