Boy playing Costco piano wows shoppers

Some kids get bored shopping with their parents at Costco. Others put on a concert.

A fedora-wearing kid named Felipe did just that, tickling the ivories in the store's music department.

Shopper Jonathan Velasquez caught the impressive impromptu performance of Vittorio Monti’s "Czardas" on camera.

"Felipe is hardly even bothered by strangers with video cameras, as his fingers glide across the 88 keys and he works the foot pedals," Velasquez wrote on YouTube. "All without a stool or parent in sight!"

The performance was uploaded to YouTube in 2011 but is only now going viral.
