From Smooth McGroove:

The Shovel Knight soundtrack has tons of amazing songs, and I took my sweet time deciding that this would be the first one I’d do. It’s not the first song I started working on from this game, but turns out it’s the first one I finished xD Jake Kaufman is one of the greatest modern video game composers, and if you haven’t listened to this soundtrack, do yourself a favor and check it out. This acapella is easily one of the most technically difficult I’ve ever done on my channel, and I hope you enjoy the work I put into it!
