I guess I can see some of the Korn comparison, but it is not very pronounced at all. You could have a good case for the guitar tone on some of the riffs, but that is being absurdly picky. Absurdly. The Korn influence just isn't there much at all, if at all. There is a very strong influence from Faith No More, on the other hand, and especially from Mike Patton's vocal stylings used in Faith No More. Of course, that's always been an influence in all of Pain of Salvation's music, but it is more prominent on this album than ever, and as of right now, Scarsick is definitely up there with Pain of Salvation's best albums, though I'm fairly certain that the lyrics are absolutely horrid. IGNORING THAT THOUGH, the music is top notch. It takes the most accessible portions of Pain of Salvation's sound and expands on them thoroughly. The music is just very, very tight. There are a lot of songs ranged from seven to eight minutes, but they never feel excessive. Everything still seems to end timely and finishes before you are sick of it. The only song that they push this rule on is on the final song, Enter Rain. Kingdom of Loss and Cribcaged takes the basic Pain of Salvation formula for ballads and tightens it to perfection. Both are a joy to listen to and are definitely two of their best ballads. Disco Queen is easily the greatest achievement Pain of Salvation will ever make. It is impossible for them to top what they created with that song. Impossible. Just a wonderful album, really. I can understand complaints about both America and Enter Rain, but any other complaints I simply will not allow!
Final edit: Also, if anyone wants to make the case that it simply isn't very progressive, then I will first ask you to give me a strict, universal definition of that term, then I will point to Disco Queen, say nothing else, and walk away.
