This awesome box set is by far the easiest (and probably cheapest, as long as you have the money to drop all at once) way to get all of the Zombies' released material--and then some!  You really have to hand it to Big Beat--the Zombies' catalogue (particularly the singles) has been repackaged & re-released time and time again almost since their breakup...but with Zombie Heaven, Big Beat delivers the Zombies' entire works on four CD's, all of which are filled nearly to the brim (a standard CD holds 80 minutes of sound, and all four programs here are in excess of 70).  That's not all you get, however.  Also included is an invaluable 68-page book with information on every track and a comprehensive history of the group, told mostly by the Zombies themselves.
