Lets call it evolution, many maybe dont like it, niether do i. But with rock music its the same thing. Just check out this link, i know it all in dutch. But this is about a rockmusic contest. I always thought rock was like metal mostly made with guitars, a bass, drums and a vocalist, and sometimes something extra. There a movie clip of the winner on the page.

Ouch. Those vocals were painful.

I don't get pitchy vocalists. If you can't sing, don't?
