"Knocking on Heaven's Door" has to be one of Guns 'N Roses' biggest classics, and one of the most covered songs in the realm of YouTube. LRRG jdachiardi's cover however it's a bit different than the rest. Instead of just playing the chords at a similar speed than the original, he slows it down quite a bit, and using his own tone of voice, instead of trying to match that of Axl Rose's (thank God), he ends up with a nice and relaxed version of the song. This one is really worth a listen.
