I think that what bosk says might be true to a certain level, but there's something that also has to be taken into account: Portnoy plays TAMA drums, Mangini plays PEARL, and those two brands sound entirely different. Portnoy plays Sabian cymbals and Mangini plays Zidjian symbals, and those two brands sound entirely different. They play in entirely different styles, they use different mics, their drum placement in the studio is different so the bleed from each mic signal will affect the overall sound of the entire thing. Mangini is MUCH more precise metronome-wise, so no wonder he sounds like a human machine sometimes as opposed to Portnoy, who usually has a very organic/flawed sound to his playing.
Honestly, I don't think it is a Tama vs. Pearl or a Sabian vs. Zildjian thing at all. Yes, they sound different. But two things to consider:
1. There are LOTS of artists that play Pearl and/or Zildjian that sound amazing.
2. Live recordings of Mangini typically sound MUCH better.
That leads me to believe it is strictly a recording and production issue, and not an instrument/playing issue.
One thing is for certain, I don't know if there's a Portnoy record that sounds bad drum-wise. His recordings are usually amazing.
That is true NOW, but I wouldn't say that was the case from the get-go. WDADU...everything sounds bad, so you can't really single out the drums. With I&W, I don't think he has a great drum sound, even aside from the triggered snare. Awake is better, but still lacking. But from then on, I agree. I think Portnoy learned fairly early on how to capture a good drum sound, and has worked with guys at the production stage who get it as well, and he has benefitted from that.
The overall drum producing experience with both drummers seems like an entirely different beast, and we had been used to a certian drum sound for over 20 years so getting something different can be distracting at first.
Yes. And, to some degree, I get that it is just "different," and I try to back off my own preferences and what I am "used to" when offering any critique. But that said, while I wouldn't say the drum sound is "bad," it could be a lot better than it is, and a lot of fans have recognized that. It isn't just that it is different and may not fit our preferences based on DT's past sound. We just feel that it definitely could benefit from being improved.
