Just out on Firehouse 12 Records via Bandcamp. The 3-CD edition has 3 full-disk compositions, Pillars I, Pillars II, and Pillars III. The digital edition has a 4th composition, Pillars IV, made of 4 parts, Part 1, Part 2, Part 3, and Part 4. Roon has different metadata for the two editions, but neither is right. I was able to edit the CD metadata version to do more or less the right thing, but the metadata for digital edition is too mangled to be editable.
Update: Added WORK and PART tags to track files, no improvement.
