So, this actually happened. Linkin Park performed a live acoustic cover of world dominating Adele and her lead single from her album 21, "Rolling In The Deep". The most surprising thing, it's pretty decent and I was expecting it to be, well not so great. It was performed by Mike Shinoda on acoustic guitar while Chester showed his lungs off with the vocals and he does a pretty decent job. It was recorded in Hamburg and you can see the results for yourself at the top via NME.
