A great interview. I don't remember having seen this before. It's out there since Autumn 2011!
One more thing, even though I think it's lame that such a dull opener follows such a cool experimental track, I think it really sums up the album in a nutshell. There are parts of the album that take Maiden to new places, but it's all based around things they've done before. They're furthering their sound using existing ideas.
