Steve Hyden goes long on lost albums:
These are the three kinds of “lost” albums I am interested in:
1. Albums that remain unreleased, either by artist’s choice or record-label maleficence.
2. Albums that were unreleased for a time but then came out after they achieved iconic
“lost” status, to the point where even now they still seem “lost” even though they technically aren’t anymore.3. Albums that might not actually exist.
