The Happy Jazz Band was formed in 1962 by Jim Cullum with his son, Jim Cullum, Jr. in San Antonio, Texas. Devoted to jazz from between the World Wars, the Happy Jazz Band was perhaps the foremost exponent of Dixieland in the Southwest. Jim Cullum, Jr. continued the band after his father passed as the Jim Cullum Jazz Band. The Jim Cullum Collection consists of tape recordings of the Happy Jazz Band and the Jim Cullum Jazz Band and covers over thirty years of the band's performances.
The James Schwabacher Collection consists of sound recordings, correspondence, scores, scrapbooks, clippings, programs, teaching material and other papers from San Francisco philanthropist and lyric tenor James Schwabacher.
The Judith Rosen Collection consists of unpublished recordings of performances, lectures, and radio programs concerning classical music, focusing on twentieth century composition, as well as women musicians and composers.
Papers and recordings from American conductor and composer Gerhard Samuel (1924-2008), particularly from his years conducting the Oakland Symphony, Minneapolis Symphony, and University of Cincinnati Philharmonia Orchestra.
The Richard Maxfield Collection consists of electronic music written by Maxfield on open reel tape from 1959 to 1964. Some tape boxes appear annotated by the composer. Nine are labeled as distinct works, while two others are more likely to be work tapes or copies. Pastoral Symphony, Amazing Grace and Cough Music are some of his more canonical pieces, and date from the period considered his most prolific. Maxfield would edit tapes for each performance to ensure a unique event, and it is unknown what versions these recordings represent.
Denis Condon (1933-2012) trained at the Sydney Conservatory and became a music teacher and educator. He developed an interest in the reproducing player piano when his father purchased an Ampico piano when Denis was fifteen. Over the next sixty years he amassed a collection of over 7500 piano rolls and ten instruments. From his home he hosted social evenings every two months where rolls were played for the assembled guests.
The noted Australian composer and pianist, Larry Sitsky, is also the author of The Classical Reproducing Piano Roll: A Catalogue Index. This comprehensive rollography represents years of work documenting all known reproducing piano rolls of classical music ever issued. In compiling this listing, he acquired photocopies of rare piano roll catalogs consisting of about 250 volumes. In addition, he collected another 80 volumes of original catalogs.
