Linkin Park have never been your traditional act. Start by having two vocalists -- one a powerful belter while the other comes from a hip-hop background. Add in a DJ/programmer, and then layer that on top of the traditional guitar, bass and drums. That gives them plenty of space to experiment. But with a new album en route and the guitar heavy 'Guilty All the Same' just hitting the airwaves, it's not a reach to suggest we may be hearing more guitar than ever from the band.
