Lara6683 is the Youtube channel of a girl named Lara who makes wonderful cover songs of game music with a piano and violin. She is a very talented musician and quickly developing a following of loyal fans. Lara is from Sydney Australia and is classically trained in piano and violin. She sings too, but has yet to put videos of her singing online.
Here is a video of her playing Nyan Cat and Rebecca Black simultaneously on the piano:
In this video, Lara does a beautifal cover of the song Still Alive from the game Portal:
Another thing she is known for is her costumes. She often dresses up as the character from the song she is playing. In this one she is dressed as Lara Croft from Tomb Raider.
I have a feeling this Lara and her channel are going to become very popular very soon!
