So for today's musical dose of cute, I give you these awesome kids calling themselves the Joyous String Quartet, doing a spirited rendition of Katy Perry's "Fireworks" in color-coordinated coolness.
Based in Long Island, these kids have apparently been playing together since they were four years old, and have made TV appearances in Korean and China. And they rock. You may recognize 8-year-old Justin Yu, the moppy-haired kid rocking the cello, who has appeared and performed on The Ellen DeGeneres Show.
Take a look:
Their collective intensity is both cool and ridiculously cute. And expert bow raise at the end there.
