Home Free is a 5 man acapella group I've followed for a while. They've got a range of voices and either an incredible "beat boxer" or they're cheating ;) In any case, it's a pleasure listening to them sing and here are a few of my favorites by them:
You can tell they had fun making this one. Good song and singing, what's not to like?
A Home Free cover of Try Everything by Shakira
They tend toward country songs but it's a mix. They did an excellent job at mixing new chords with smooth singing on this song, originally written by John Denver.
A Home Free cover of Take Me Home Country Roads
This song by Alison Krauss and The Union Station has a lot of covers. Check some of the other ones out as well, but his is the Home Free version
Man Of Constant Sorrow cover by Home Free
Enjoy
