Uhm. Free and open is fine, but good performances and recordings is arguably is more important – otherwise, you might as well just preserve the sheet music.
If it isn’t a performance worth listening to, it isn’t worth archiving. And I’m really not convinced it’s worth video, especially given recent evidence that when we can see the performer our reaction is often strongly affected by performance skills other than musical skills.
Toward that end, the more performances/recordings the better… but it feels to me like the priorities of this particular project are backward. Preservation is barely an issue for this music.
