I give Lord Bif Music a lot of attention on the site, but if you've seen his videos you understand why. It blows my mind that someone who can transform game music in such a unique way isn't at the top of Youtube every time he releases a video!
His latest video is a Jazz-rock cover of the main theme from Hearthstone, and it's one you'll want to listen to again and again. Take a listen below, and be sure to check out his other work on the site here and here.
