It's not really Rock.
It's really not Rock.
If you're looking for some Dnb and Rock music I'd suggest to take a look at the band called "EGOIST".
It's a japanese band that has made some songs for the opening/ending of a few Anime.
This band has a particularly great sound that blends perfectly DnB and Rock. An example would be "Namae no nai Kaibutsu".
That song is soooo freaking good.
