Hmmmmm. I gotta give Gene and Paul credit where credit is due. I think even they knew that a Volume 4 set featuring just stuff with Eric Singer and Tommy Thayer would not sell as well. So, what they have done is gone back to the vault from all incarnations of the band to give it a good variety of material to satisfy those long time KISS fans. Ahem. Still remains to be seen what the bonus disk will be at Amazon, Best Buy and Walmart. Not sure about Target getting one yet. To be released late November, just in time for Xmas.
