This collection consists primarily of field recordings of Cape Breton and Irish traditional music performed by various musicians in the Boston area, as recorded on home recording equipment by Johnny and Mary Muise. Included are informal music gatherings and social events that took place in the Muise home in Dorchester (1951-1965) and Roslindale (1965 and later), as well as concerts and other gatherings. Some of the audio recordings also contain published material.

Collection is open for research. Open reel tapes and audiocassettes are restricted (boxes 2-6). All open reel tapes have been reformatted, and digital versions are available for use in the Burns Library Reading Room. All audiocassettes have not yet been reformatted, but can be upon request. Note that there may be a delay in availability of digitized versions.
