Home Free, the only country acapella group on the NBC reality show 'The Sing-Off,' made their debut with 'Cruise.'  Last night they took on Rascal Flatts 'Life is a Highway.' The judges raved about their performance, sending them to the next round in the competition.

I've loved both performances and can't wait to hear more.  There's nothing like acapella music to hear true talent.  No instruments, just beautiful voices.

Watch Home Free on 'The Sing-Off' on NBC tonight at 8.
