Linkin Park is a metal/rap band group that was started in 1996.  I am unfamiliar with this band but I have heard of them, and apparently their music is very popular.  The logo that they use now is part of the art from a successful 2007 album.  I don't know who designed the logo, but I like the symbol and font that is used in the logo.  The symbol has a lot of movement to keep the viewer interested.  I didn't notice this at first but there is an L and P in the symbol.
