I have two CDs, “Bird/The Savoy Recordings (Master Takes) Vol. 1” and Vol. 2. They were separate US releases, on Savoy Jazz, probably in the 80s, 14 and 16 tracks respectively. (This discogs entry is virtually identical to my vol. 1, except mine isn’t a record club edition.)
Using Picard ‘Scan’, 29 of 30 match to the Bird: The Savoy Recordings (Master Takes), a 2005 release from Columbia Japan. (The 30th, “Half Nelson”, seems like a very near match by fingerprint as well.)
Would it be better to create two new release groups, one for each of my CDs? Or add them as separate releases under the existing release group even though each one is only half of the existing release?
