I'm sure at least some of you know the big four. If you haven't, the big four is just the four biggest thrash bands, Metallica, Megadeth, Anthrax, and Slayer. They are having a long anticipated concert in Poland. Unfortunately, its not a tour, just a concert, and its just in Poland. However, you can see it live in Theatres worldwide, as I heard. The question I have for you is, are you going to see it?
