Ok so theres technicality here and you're clearly paying close attention but the only time I personally ever noticed any drumming issue with Nicko was on the Future Past. That's one noticeable drumming issue over maybe 10 or 11 gigs since 96. I've seen them with Simon 4 times and and I've noticed dodgy drumming (clunky transitions, parts simplified to the songs detriment) each and every time.
Now, I'm not as pissed about this as some are, the 4 Simon gigs I've seen have been great experiences and Paris was one of the best I've ever seen but the issues are undeniable. And it's not just tempo. Generally I won't notice tempo changes unless they are extreme. Like Hallowed in Dublin last year. It shocked me how slow it felt. I honestly thought they were a busted flush right there and then. But I didn't notice it being slow at the other gigs. Anyway, tempo isn't my main issue, it's the changes, transitions, like after the slow bit in Rime, for example. It used to be bombastic. It no longer is, not to me. There's a lack of dynamics with Simon which I see as an indisputable fact. It just comes down to how many fucks each individual gives about it.
If any band member has told him to play that way it's only because they know he can't manage the tempo and flair of the original transitions together so they sided with tempo.
