The Zombies

The more we learn about the musical DNA behind Eminem's new 'Marshall Mathers LP 2,' the more it looks like a classic-rock radio playlist. In addition to sampling Billy Squier and Joe Walsh for his latest album, he also ended up turning to a Zombies classic for support.

Terms like "classic" and "amazing" get tossed around an awful lot when talking about albums. Those words have been used and abused over time to the point where they are almost meaningless. Here to reclaim the significance of those terms is an album that truly is amazing and a drop-dead classic, the Zombies' 'Odessey and Oracle' -- which was released 45 years ago.
