The track “Macbeth (intro)” heard on Vader’s live album “The Darkest Age” is actually “Agnus Dei (Acropolis)” by Laibach played from tape, with crowd noises and a greeting from the band towards the end.
I’m wondering how we could reflect this in the database. What Vader is doing is not a cover, and I’m not sure it even should have a distinct work (it has one right now). Even if Vader recording was linked directly to Laibach work, what relationship should be used?
I was looking at available recording-work and work-work relationships, but I didn’t find anything that looks suitable for this situation. Any ideas?
