AAF were one of the first bands I got into when I started listening to rock/metal... it was all over mtv2 at a time when mtv2 was actually decent (along with the likes of Linkin Park, Drowning Pool, Soil and Marilyn Manson)
Yeah I get that that the shouty stuff is not for everyone... at least in the Borknagar its used sparingly, almost for creative effect...
I love the shouty stuff, but even I can't listen to it all the time, need some softer more mellow stuff to balance it out.
