My brother Matthew and his friend Lewis formed an acoustic Linkin Park cover duo/band very late last year. They've covered many songs acoustically, which can be viewed below. They aren't doing any new covers as far as I am aware, so head on over to their YouTube channel and get them to make more, because I don't think me telling him will work. LOL.
Here are their covers:
Bleed It Out
New Divide (w/ The Catalyst)
They also made a VLog, and here is a live version of Crawling.
