Straight No Chaser A Cappella
If you haven't jumped on the a cappella bandwagon yet, this group just might get to you. Straight No Chaser is an a cappella group that was formed at Indiana University, but has been reassembled and made into so much more than it once was. Combining all of your favorite songs with a little comedy (and let us not forget the classic suits) makes for an incredible performance.
I would highly recommend spending as much time on their website or YouTube channel as you can afford, because it's worth it I can assure you.
Check out some of my favorite covers here:
I'm Yours/Somewhere Over the Rainbow
The Lion Sleeps Tonight
Rolling In the Deep
