Check out the Lemon Song by Virtual Zeppelin. It's absolutely incredible! This is just the first to come of many Zeppelin covers by these guys.
I looked into what Virtual Zeppelin was all about and found that these guys are musicians thousands of miles apart and have managed to put together the best Led Zeppelin covers ever recorded.
They can play Led Zeppelin with freakish accuracy. The fact that they live tens of thousands of miles apart—from Canada to Japan to Northern Virginia—is no longer a barrier to putting together the best Led Zeppelin cover band in history.
Each guy records his part. They pass around multitrack files along with individual videos, and the last guy in the chain mixes everything down into the finished product. These guys didn't go looking for a decent singer in the next county. They went looking for the absolute best Robert Plant impressionist and found him on the other side of the world. And what they created was something much greater than any of them individually could have mustered!
