Welcome Andrew.
On the 'Killers' album Adrian was a really good guitarist but probably not in Dave's league.
I find Adrian's solos on
Killers much more memorable than his on
The Number of the Beast.
His solo on Hallowed is weak and apart from a few nice moments on 22, The Prisoner and Children of the Damned there isn't much to write home about. His licks in Wrathchild, his sparkling solos in The Ides of March and Prodigal Son... now we're talking. However, I admit that Adrian became better and this can already be heard on
Piece of Mind.
Never thought he was "better" than Dave. Dave's solos kept being entertaining and imo it wasn't til
The Final Frontier when Adrian clearly, really had nicer solos than the other two guitarists. Alright, on
Somewhere in Time, Adrian might have outshined Dave a bit, but probably because he did more solos. Dave's intro solo from Deja-vu and his great runs on Caught Somewhere in Time and Heaven Can Wait are as memorable as Adrians best solos (bar his on Sea of Madness), I think.
Dave always sounded like the one who played with more ease. It's not that this was better thing, it's just very nice to have that besides Adrian's constructed solos. Dave was the one with the fluent touch, and the brighter sound. Take his slow solo on Powerslave or e.g. his solos on Judas My Guide or Weekend Warrior (check that build-up!). I could go on for a while. Very good stuff. Janick did some really nice things as well. E.g. The Clansman, Ghost of the Navigator, The Pilgrim and The Legacy have solos that I enjoy very, very much.
Songwriter
As others have said, Adrian is undoubtedly the one most open to new ideas and experimentation.
I'd say there were experimental things going on in the nineties (though not per se on
Virtual XI, or on
No Prayer, if one sees that one as a "return" to raw sound).
he was writing the best songs on the albums.
Not at all. I find Sea of Madness the best song from
Somewhere in Time, but his other two I do not rate higher than Deja-vu or any of the Harris songs (apart from Heaven Can Wait). Actually, Adrian was the best songwriter on
The Final Frontier, and he wrote one of the best songs on
Dance of Death (I still think the title track is better though), but on all other albums,
other people wrote the best songs. Even in 1988. The Evil is a fantastic track from
SSOASS. But I prefer the long ignored title track, Infinite Dreams, The Clairvoyant and Only the Good Die Young. On
A Matter of Life and Death, it's still kind of equal, in my ears. Songwriting, Lord of Light and BTATS are indeed the best, but both Dave and Janick play some damn fine solos as well. I think I like them even better than Adrian's solos on that album. Coincidentally (or not) I am talking about Janick's solos on the songs he co-wrote and Dave's on the one he co-wrote.
I think Bruce knew it wasn't the same after Adrian had gone and when he left it came as no surprise to me. To be honest it was a relief as he was awful on his last tour and the farewell tour they did for him was frankly embarrassing he was so disinterested.
I don't think Bruce going away from Maiden had anything to do with Smith. If you can point out on source where he hints to that, I'd be interested to read it.
All in all, I think Adrian is the most creative songwriter since 2006 and the most interesting guitar player on
The Final Frontier, and perhaps on
Somewhere in Time.
