Justin Bieber

A super precocious, multi-talented and self-taught musician (drums, guitar, piano and trumpet) 15-year-old Justin Bieber was already a phenomenon on YouTube -- putting his impeccable spin on songs from artists like Usher, Ne-Yo and Stevie Wonder -- before the world took notice. Since 2007, Justin racked up over 10,000,000 views purely from word of mouth.

But then he started to bubble up and important folks took notice. Seven months after Justin started posting his videos online; the Canadian teen flew to Atlanta, GA to meet with R&B sensation Usher, who quickly took him under his wing, making him his newest protégé. Shortly thereafter, Justin Bieber also wowed Island Def Jam head Antonio "L.A." Reid and has never looked back.

His first single, "One Time," produced by Chris "Tricky" Stewart is already putting him on the map and his debut album My World is due later this summer. At just a wee 15-years-of-age, Bieber is a virtually untapped well of natural artistic talent, and presumably will be a solid force in music for many years to come.
