NYC Firefighter Rocks the National Anthem on Guitar [VIDEO]

A New York City firefighter named Louis DeRosa of Ladder 15 shredded the national anthem on his guitar outside of New York-Presbyterian Hospital a few days back. It was part of the city's nightly salute to healthcare workers.

And when we say "shredded," we mean it. He went full-onJimi Hendrix, as his fellow firefighters stood beside him on top of the fire engine.
