Unofficial recordings on cassette tape of whole performances of plays and operas participated in by opera singer and Chapman University Artist-in-Residence Carol Neblett, from 1972-1995. These are likely unofficial recordings that Neblett had someone create during her public performances (as well as whole productions), with which she later used as reference.
