If you don't like Johnny Cash then you just don't love Country, man. You have to be careful when you cover a Cash tune and the group Home Free nailed it.

If you watch the NBC hit show, The Sing Off, then you will most likely have heard of the season 4 winners.

The group Home Free, based out of Minnesota is an a cappella group that will blow you away, if you're into that kind of thing of course. I still love the sounds of a good old fashioned Barbershop Quartet and Home Free is as close as you can get...with five guys.

Check out their cover of the legendary tune by Johnny Cash and let me know what you think. There is no grey matter on this one...I'm thinking you'll either love it or you're going to hate it.

If you're interested in seeing the group live, you can catch them on Friday, October 10, in Salina, Kansas.
