Charlie Siem performing in a concert. Siem says the challenge of classical music is to keep it fresh, "making (classical music) not just a sort of museum piece in a glass case, but make it fun and relevant and fresh to an audience today."

Charlie Siem began playing the violin at an early age and didn't want to stop -- even when his parents asked him to do so.

He said, "(My parents) initially obviously were sort of, 'Great, you know, Charlie's playing the violin, it's great for the kids to do a bit of music.' But when I took it to the next level, and I was like, 'No, I wanna play the violin then they got a bit worried.'"

Charlie Siem's parents insisted he get an education. He went on to Cambridge -- where he began modeling on the side -- and honing not only his talents on the violin, but his very unique style of performing.

Siem's modern presentation of 200-year-old music caught the eye of another fashion-forward musician -- Lady Gaga. Charlie not only performed at a party in Gaga's honor, but he has also shared the stage with the legendary rock band, The Who.
