Quite simply, this album carries on where adrenaline left off, but takes the 'tones sound to a new level. The melodies are better, the lyrics are more acclomplished. This album has the trademark 'huge' sound, which adrenaline seemed to be missing. Adrenaline is fantastic, but ATF is simply a natural advancement for the 'tones. From here, they have carried on this kind of sound on white pony, and deftones, but have not bettered it. This album has also got their two best songs - my own summer, and be quiet and drive. Apart from those, look out for mascara, ATF, and the hidden track, as standout moments.
If you like nu metal, but want something more sophisticated, heavier, and ultimately far superior, then this and white pony are the albums to get. Equally, if you're into metallica, etc. but want to get into more modern music, then deftones are the band for you. Either way, get ATF, because it is THE BEST!!
