Is it appropriate to add unrecorded works to the database? I’m not sure how to interpret the documentation: https://musicbrainz.org/doc/Style/Classical/Works
“Works belonging to the ‘classical music’ genre should have at least one known recording or performance (even if it is not currently in the MB database).”
“Lost and/or unrecorded music can be entered if necessary for correct relationships and/or to make a composer’s complete catalogue available.”
I’m specifically talking about Anthony Braxton, here. I have a copy of his Composition Notes, and it has a list of his first 132 compositions, but some of them have not been recorded in any form. Composition No. 120, could be useful as it acts as a ‘container’ for several constituent parts that have been performed, even though the whole composition (theoretically an opera), has not been performed (or, at least recorded and commercially released).
