I really like that Monument. Probably because it's so early Maiden.
I like BoS too, more than any of the reunion albums, but I've not given most of them much time, AMOLAD apart.
On a similar subject to the Monument/Maiden thing, played Voodoo Circle's last one yesterday and mostly enjoyed it. I'm with Brent on the ' influence ' thing. As long as it isn't plagiarism I'm ok with it. VC often fall foul of that though.
