GTA fan and YouTube musician extraordinaire SquidPhysics released some pretty impressive covers of past Grand Theft Auto theme songs. He proves himself to be quite the Renaissance man - filming, recording, mixing, and playing a wide array of instruments, including the classic violin, the saxophone and the cello as well as a few of the more eclectic instruments like castanets and bongos and found sounds via beer bottles, markers and spray paint. Check out his cover of the theme from GTAIV below
