What not to do if your bird sh#$% on you....
It seems to me that it was mostly various reviewers that were claiming the material was "complex".Well, a striped down approach would have worked just fine if Maiden did not promote their music as complex, progressive and with "a lot going on in there". Cause it takes a child to tell that in al ums like SSOASS and SIT there were 10 times as much density in half the length.
Progressive can mean many different things.
And 10x the density? Really?
