you forget....people who like clean / power metal vocals only like the death vocals when Glen from ProgPower tells them the band is good. then they will like it.
the only thing new I got this past week was two early Mago De Oz disc....both of which are great. I am really enjoying the "Belfast" disc....I was really surpised when the singer for Astral Doors/Wuthering Hieghts did one song.
Maybe they just need someone to introduce them to a certain band. A long time ago I wouldn't be caught dead listening to black metal, that all changed when I saw Immortal live.
