They are so cool and clever. I love them even though I just seen their performance days ago.
The video below was the first song I heard from the group. It is all about Christmas though this will be a perfect timing.
They have a lot more songs you can view in YouTube .
As far as I know, they were known after they won from "The Sing-Off" tv show contest.
I am not familiar with that one. I just have read them in Wikipedia.
"Penta for five persons" and " Tonix I think it comes from the word tone" and they made music with no instrument at all.
Anyway, I expect that you play the video now. What do you think about their song?
