How would you enter something like this? I tend to add this as a single standalone-recording with the name of the album (“Gothic”) or maybe as titled on the stream page (“Live at Roadburn 2017” or “Gothic Live at Roadburn 2017”?) and link it to the . This could be related to the individual works for each song performed as “live recording” and also be related to the event. Or any better idea?
I went ahead and added the standalone recording with relationships, see https://musicbrainz.org/recording/b3cb5ada-d623-47ac-879d-ca6ac12497d2/edits
It makes sense to me how you handled it.
Same. I likely would have done the same thing.
