Big Four Comes to America, for one show only

Metallica, Megadeth, Slayer and Anthrax are coming to America to do just one show near LA in Southern California on April 23rd. For those who don't know, these are the four best Thrash metal bands from the 80's. They did a seven show tour across Europe together in 2008. Now after much demand, they are coming to do one show in the US.

But its weird that they are doing only one show, and its on the west coast. Good for those who live in Cali, but sucks for those on the East Coast. Europe got seven, so why can't the US? Plus aren't the bands from here?  It confuse's me, but for those who are able to afford the 100 dollar ticket price and are able to get down there, I'm sure it will be one hell of a show. Also very crazy, according to the Youtube video that is advertising the show, it's a seven hour concert with full sets from each band.

Wish I could go, but it's a little to expensive. Anyway, for those interested, you should be aware that tickets go on sale on Jan 28th, so get your wallets ready.
