Mullmaniac, there's no heart in Jimi's cover of Bob Dylan's "All Along the Watchtower"? Because, in my opinion, this is the greatest cover of all time and clearly defines the role of a cover. It shouldn't be play the song straight through, because that's boring and offers no incentive to listen to anything but the original. The role of a cover is to take the song and make it your own, like Jimi did. Everything in the recording, from the acoustic's strumming rhythm, to the delivery of the lyrics, to (of course) the landmark solo is so distinctly Jimi, even though it's a Dylan song. The result is that is takes the original to new heights and becomes a completely different artistic statement altogether.
