All albums are regular U.S. releases. The first two releases of
1997 and 1998 can be found for extremely low prices on the used-CD market, though
the 1998 DVD Audio album reached a value of at least $35. The prices of the 2012
albums originally ranged from $12 for the 2-CD version to $22 for the 4-CD set.
The cover art of all the releases' international pressings will vary. No promotional
release was ever issued and no bootleg has entered circulation.
