I saw Slayer, Megadeth and Annihilator live once and they really kicked ass.....I was in the mosh pit at that time and I still need to know who's blood was on my tee:):)!!!! KILLER ROCK :)
On the contrary, packaging and cover art are very important aspects of music seeing that we live in a visual world.....the daZe of radio and simple audio are OVER!!:):)
