When you think of powerful vocal performances, Johnny Van Zant of Lynyrd Skynyrd may not be first on your list. Hell, he may not even be on your list!

But, after listening to his isolated vocal track from Skynyrd's 1973 hit "Simple Man," you might have to rearrange your list a bit.

Maxim posted the track the other day and it has quickly gone viral. We're confident that no artist today could even come close to a performance like this! (And, it's way better than the isolated David Lee Roth vocals we came across a few years ago.)
