Iron Maiden - Seventh Son of a Seventh Son
I bought this one based partly on listening to samples at Amazon, and also because I read in more than one place that they had heavily used synthesizers, so I thought the sound of this one might appeal to me more.
I really like it. So far my favorite track is "Can I Play With Madness."
I'm sure I'll get more of their stuff in the future, but for now I'm probably going to go in a completely different direction for the next couple of albums that I'll get with my self-imposed music allowance.
