High above the city of Charlotte in an uptown condo, you’ll find an impromptu treat. There’s a man sitting at a piano – someone you’re used to seeing play something very different.

“I have one extreme where I play this physical sport getting tackled, hitting people, (with) blood, bruises, breaks,” says Panthers’ running back Jonathan Stewart. “And then you have the piano where you let your mind just travel.”

Stewart says that off the football field, there’s another side to a lot of players. For him, it’s music.

Dare I say it’s the softer, gentler sensitive side to Stewart?

“Not sensitive, he says, pausing. “No, I am sensitive!”

Stewart will get to show off his other passion Friday at a benefit concert for the Charlotte Symphony. “Classical Idol,” which will feature a diverse group of musicians, singers and other artists, will be held at 7:30 p.m. Friday at McGlohon Theater in Spirit Square.

Stewart says he grew up in a musical household and picked up piano on his own. He said a big part of playing is being creative, and learning different types of music. “I don’t read notes, I play by ear,” he said.

The music is even part of his game day routine.

“We wake up in the morning at the hotel, come back here, change clothes… tickle the piano for a little bit and then head to the game.”
