I like the drum sound on that record. I think it fits with the songs really well. I couldn't imagine it any other way. If you listen to "Noone Knows" you can hear the room sound, in fact the snare isn't perfectly in phase, it's very wide sounding. The room is just very tight and controlled, almost no decay at all. They obviously weren't going for a big room sound ala "John Bonham" but a harder, punchier sound.
My CD came with a DVD that has a lot of live footage as well as some studio shots of them working on the record. kinda cool.
And it wouldn't be the first time Grohl has overdubbed cymbals... go listen to the HiHat on"Everlong" off "The Color and the Shape" FF record.
