The second series, Concert Seasons Files, includes newspaper articles, programs, board and committee minutes, board correspondence, and other documents, arranged by season. The season ran from July-June each year.

Box 13 includes some oversize posters and newspaper pages.

Photographic Images & Sound Recordings basically include promotion photographs of guest artists, but also include photographs of a few board members, conductors, and symphony members. A few oversize group portraits are also included here. A few newspaper clippings are also interspersed throughout.

Lastly, the Related Organizations series consists of newspaper clippings, programs, and other miscellaneous items relating to predecessor musical groups in La Crosse. The most prominent include the Cathedral Orchestra, La Crosse Philharmonic Orchestra, La Crosse Vocational Civic Symphony Orchestra, and La Crosse Symphony Orchestra (pre 1947).
