I wasn't speaking about any particular Maiden solo or even any specific piece of music - I was merely answering the general question "what's the point of doubling parts". (I probably should have made that clear in the first place.)
Alright. I love the energy and the rawness of it. And the speed, of both TETMD and FOTD. Later the band stated they played some songs so fast that it became ridiculous. That's easy talking, in hindsight. I never thought it sounded ridiculous ('Arry and Nicko always wanted to play Flight of Icarus way faster for example) and to me it rather sounds like an excuses (perhaps they are not able to play some songs so fast anymore as they could)
p/s: Please forgive me for my horrible english
