Slipknot

Yes, this is Aggressive Metalcore, and I didn't even try to classify the style of Korn; in my opinion, it's just Alternative Hard Rock....

no, not hard rock:smile38:, but hardcore;)

Well, regarding the album Lost And Found (2005), it's their best so far....

hmm...

You can also listen to the band Trivium (Metalcore / Melodic Death), or Engel (Melodic Death / Metalcore) (although there's nothing special about the album, it's still good)....

I think I've heard of Trivium, but if I don't have it, it means I didn't like it:(

but I'll probably check out this Engel.

It seems that we have different ideas about metalcore (although it's not surprising - this style is considered a mix of several genres). But I imagine it something like what its representatives play, such as A7X or As I Lay Dying (if you've heard anything from them).
