As of my last knowledge update in October 2023, there is limited widely recognized information about an artist named Mary Bruce. It is possible that she could be an emerging artist or a local musician not extensively documented in mainstream music history. If you are referring to a specific Mary Bruce in a particular genre or context, please provide additional details. Alternatively, it may also be beneficial to check recent music platforms or local listings for more current information on her works and contributions to music. If you meant a different artist or have more context, please let me know!
