A Slice of Acoustic Heaven...Pentatonix's Little Drummer Boy

I came across a post by The Blaze, gushing over an acapella rendition of Little Drummer Boy... and I had to click on the link to see.  I HAD to see anyone deliver this oldie in a fresh and amazing way (I have to admit I was sceptical).

I WAS BLOWN AWAY.

I WAS STUNNED SILENT.
