Could be just me, but Chocolate Starfish is just too damn loud mastering wise.
I compare it to Hybrid Theory (I was never a fan of Linkin Park back in the day, but I got it last year finally, and honestly the album has some damn good rhythm playing, grooves and some tight as shit bass playing as well, as well as some monstrous production and mix for an album that came out in 2000) and damn, it sounds like it's being strangled and gasping for air and to me it has this annoying slight pumping sound to it that Hybrid Theory doesn't have
I'm not anti-loudness wars guy by any means, I like loud masters (Stabbing the Drama, Riot! by Paramore and The Way of All Flesh are some of my fave productions and none are particularly quiet albums), but shit I think Chocolate Starfish was definitely one of those albums that really set the gears turning for just starting push shit too far in mastering.
Also something I noticed lately, because now that I've got the albums, is the scary similarities in guitar tones between some of the LB, Linkin Park and Evanescence productions and shit some songs off Riot! as well (because AFAIK they didn't use the same amp for dirty sounds for all the songs on that album). Although Chocolate Starfish does seem to have a greater serving of lower mids/sub bass on the bass tracks than Hybrid Theory.
Even before someone tells you what amp is used, you just know it's that undeniable, awesome roar of the Dual or Triple Rectifier. I just love how those amps just slot into the mix so well with their mid range qualities.
