Meet my new favorite YouTube rockstar, Brett Domino. This unassuming 27-year-old singer from Leeds, UK has covered hits by everyone from Justin Bieber to Jay-Z, and he also writes amazing original songs. His weapons of choice are the keytar and the stylophone, and he's been known to perform solo, with stone-faced sidekick Steven Peavis, or with the Brett Domino Trio.

I've gathered up some of Brett's best videos, plus his performance with the trio on "Britain's Got Talent." Hit the jump for a medley of pop hits from "Now! 75," a Katy Perry cover, a Justin Timberlake medley, and the original song 'What Would You Do (If a Shark Started Eating You?)'
