The group, Straight No Chaser formed back in the late 90s at Indiana University and when they graduated, they split up. They got back together in 2006 for a reunion and one of the guys had videos of a performance and put it up on YouTube since the members of the group were now living all over the country. By the beginning of December of 2007 about 100,000 people had seen it, which the group thought was pretty cool. But by the end of the first week of December, they had 200,000 total. By Christmas, 6 million people viewed it as well. And one of them was an executive from Atlantic Records who decided to call up and see if they wanted to get back together to capitalize on this and do a Christmas CD. And as you might be able to tell from the title of this post, they did, and it's called “Holiday Spirits.”
And it's good. They do a lot of standards as well as some fun ones, like Little Saint Nick. And they include the live version of 12 Days of Christmas, which is also good, but it's honestly better with the video. So, if you're looking for some new Christmas music, I'd give this one a shot. The production is great and the harmonies that these guys pull off is really, really excellent.
