One of my very first bands I ever started, when I was 18, had lots of promise. Great lyrics, great chord progressions, it was really right up my street. But the drummer was a jazz drummer. Pretty good drummer all round, but could he hit a snare with passion?? Could he fuck. We were trying to be the next Oceansize or Cooper Temple Clause type band (both fucking GREAT bands if you don't know them) and he was soft as shit. The music just fell on its arse, because the drummer did not understand the aesthetic, did not understand that rock music needs to be passionate, beefy, and in some cases, yes... HARD.
There's obviously all kinds of music. But if you have a drummer who is locked into their particular style, or dynamic range, and won't shift... it is a bad thing. 100%. But that doesn't just mean loud drummers being unable to go quiet..... it also means quiet drummers also being unable to go loud.
E-Kits are well known for being inaccurate in terms of transferring acoustic kit technique. You can't - and should not - play an e-kit the same way you'd play an acoustic kit. Even the manuals for these things say similar things.
Now imagine taking a drummer who had only ever played an e-kit, and putting them in a band that required some BALLS behind it ..... insto-fail in most cases, is my guess.
