Here is a link to a video the group in my signature line put out of one of the songs on their Christmas EP:
There is another link where you can listen to the entire EP (6 songs). Make sure you have the sub woofer on when you listen to it or you won't hear half of what Avi, guy in the toboggan, sings. You won't believe it is A Capella.
I made 2 DVDs for my Mom of A Capella Christmas music I found on YouTube. Some are videos, some are MP3s. There are a lot more. Let me know what you are listening to. Jim.
