I'm not a big fan of the drum sound on the first two albums myself. Definite use of either triggers or at least heavy amounts of limiting/compression/EQ to take all the life out of the drum sound and make it kinda bland, which is kind of a running theme through the production of the first two albums. Sure, you can hear all the instruments nice and clearly, but that certain something is missing that makes the whole package sound 'together'. I dunno how to really explain it properly, but that's the vibe I get. Meh, YMMV of course.
The drum sound on MAYH was a step in the right direction, but they really got their sonic shit together on Still Life.
