I was reading somewhere about Eminem's new album.  Now I've never been a fan of him especially in Black Durag, but if there was an NWA/GN'R tour talked about at one time, than I wonder if an Eminem/GN'R tour could co-exist?  It would not be for the weak of heart and you've got very unpredictable acts going back to back, each of them might even wear bandana.  The curiosity factor could generate ticket sales that you can buy here.  Maybe I'm just thinking out loud, but it is an interesting option.
