I'd still like to know why some recordings are so bad though. For instance, Grace Jones 'Nightclubbing' is a fabulous sounding recording, whereas U2's 'The Unforgettable Fire' sounds dreadful.
That's an increidibly broad question though.
There's soooo much that goes in to the recording that make a difference it's hard to know where to start.
Just look at the chain you have for recording. You've got the artists, the instruments they use, the amps they use etc. Then you have the recording studios themselves. Some are designed to sound a certain way, some are designed to be flat. Some like isolate each band member so you don't get any bleed over, some like to record in a room together. Then there's equipment - what mic's are used for each instrument, how they are placed, what are the pre-amps like in the recording devices, what mixing desk are you going through, are you using any pre recording effects.
And that's before you even start mixing, re-dubbing, re-recording, re-editing, adding effects, etc. and then the mastering etc..
Also don't forget that some bands/artists like their stuff to sound a certain way, even if for example, you don't like that sound.
So, in short, what seems like a harmless easy question is actually full of so many different things that could make it sound different there is no easy answer.
Here's a nice little artice on producing the last Paolo Nutini album, but it should give you an idea of some of things that are done to produce just one album
