Slipknot

I found and downloaded an album from 2005, released by Madway, and honestly, it doesn't smell like metalcore:( I don't know, maybe I need a different album? Recommend something.

Otherwise, it's more like Nu-Metal, but aggressive - more in the style of KoЯn,
this is probably a well-known mix called angrycore - something like that.

Yes, this is Aggressive Metalcore, and I didn't even try to classify Korn's style; in my opinion, it's just Alternative Hard Rock....
As for the album Lost And Found (2005), it's their best so far...

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

Those who have read the reviews generally speak well of Slipknot...
