Good list by Ermz, but yeah like Morgan said, I do find the guitars to be on the harsh sounding side on some of the songs on the Nickelback album. Fight For all The Wrong Reasons stands out in particular as having a kinda scratchy, annoying guitar sound IMHO. But again, as Morgan said, goddamn dynamic mix. Now if only the music was better...........
I'll have to throw in Linkin Park's "Hybrid Theory". The guitars always sounded sexy to me, that perfect amount of high and upper mids and total lack of fizz.
It also has some of that sexy Andy Wallace guitar and bass guitar blend happening. Not quite as good as the Korn album that Ermz mentioned, but pretty damn nice for an album released in 2000 nonetheless.
Another vote for Riot!, Organic Hallucinosis and Rhythm Chord & Melody.
Organic Hallucinosis just sounds like a death metal album should, which is just straight out ridiculously brutal. The music and production just go together so well for that "Gonna go and destroy buildings with heavy machinery" vibe.
Rhythm Chord & Melody is just beautiful. Song writing is just absolutely top notch and the production is the icing on the cake. Very talented band indeed.
