MILWAUKEE- At 26-years-old, many fans and critics consider Josh Groban one of the most talented young performers taking the stage today. His faithful followers call themselves "Grobanites." It's a term which seems to both bemuse and amuse him.

Groban's current tour recently passed through Milwaukee where he played to a sold out Bradley Center crowd.

He sat down with me for an exclusive interview just about an hour or so before taking the stage.

His reserved graciousness impresses those who might expect a pompous nature. He credits that "grounding" with a solid upbringing by his parents who he says always supported him. In fact it was his parents who initially realized his potential.

Groban remembers discovering the power in his voice during his teen years, "I would go out and listen to big singers, and I would come home and I'd say hey remember when that singer did this (imitates singer.) Wow it's actually there, and my parents recognized it and gave me voice lessons."

The singer admits, at that age, being different wasn't the easiest thing. In fact he even intimidated himself with his growing talent, "I was afraid of it at first. It wasn't really the thing everyone was doing.

"I was at a high school where football was the big thing, so I played football - if you can believe that - and put it (singing) on the side... (I) focused on the acting and the voice full time eventually - it came a little bit later, when I was 15 or 16."

"But it started in my teens - and I was discovered at 17."

"So from that point I decided I was really going to be a professional singer - that was like 14 or 15 - from the point I was discovered at 17. I was still just thrown into the fire and still feel like I've got a lot to learn."

In every city Groban visits he contracts with local talent to join him on stage for his finale.

In Milwaukee, the Anthony McGayhee Voices choir was chosen. These local singers who have won numerous competitions were thrilled to be afforded the opportunity. The choir acknowledged just how rare it is for a successful artist to share the spotlight with others.

Groban indicated that he brings different choirs on stage with him in part due to logistics, but more importantly to re-energize the show each night by adding local flare.
