This series contains programs from various musical organizations, theatres, and music festivals other than the Houston Symphony. The organization of this series is first geographic, then according to the type of organization, with musical organizations coming before non-musical ones, and finally chronological. In this series, Houston area programs come first, followed by American programs, and finally by European programs. Within each geographic region, musical programs come first, followed by non-musical programs (primarily for theatre productions). Some of the programs are grouped by the individual organization (e.g. Houston Grand Opera), and some are grouped together (e.g. American Symphony Orchestras). Within each grouping, the programs are arranged chronologically. Programs noted with an "*" contain Ima's handwritten notes.
