As far as single-artist boxsets are concerned, "Zombie Heaven" has always been the best IMO and the yardstick by which all other boxsets should be measured. It does everything right- great sound, logical sequencing and tons of rarities. Basically everything ever recorded by a fantastic band who wasn't along very long but had great material that wasn't widely available. Even has BBC sessions. Only way it could have been better is if it included the material on the "Into The Afterlife" comp (but that's forgivable because for the most part, that material is not technically by The Zombies).
