Now, he's nationally known like his dad and wrote most of the songs for Otter Creek.

The duo splits the profits from Otter Creek, which has sold about 1,500 copies. They tour together, too, most recently this week, when they were scheduled to perform and teach music classes at the Maidencreek Old Time Music Blandon, Pa., on July 29.

And they perform locally four times a year for the public. Next up is the Aug. 2 concert with the Honey Dewdrops, a popular traditional-music band.

Ken, himself a Friends and Johns Hopkins University graduate with a degree in Public Health, said the backyard concert "is a chance to do something a little more intimate."

Brad, who played squash in college, also teaches squash while living at home and making music with his dad.

"We hang out more," Brad said. "A lot of fathers and sons don't have that kind of relationship."

"It's been super fun for me," Ken said, adding that he's been encouraging Brad to sing.

"I don't sing," Ken said.

"You don't want to hear him sing," said Brad.

Brad is in no hurry to get on with his life and is content to live the musical life with his dad, practicing in the yard and in their home studio, a converted garage.

"For now, music is my main focus," he said. "I'm just getting to the point where I have a real passion for it. But I think playing banjo as a profession would be a real tough career."

Of course, there's always Monsterball.

"I started Monsterball in Ithaca," Brad said. "It was wildly popular."

Ken and Brad Kolodner and The Honey Dewdrops will perform Sunday, Aug. 5, 7:30 p.m. in the backyard of the Kolodners' house. If it rains, the concert will be held at the Stony Run Friends Meeting House, 5116 N. Charles St.For more information and tickets, call 4120-746-8387 or 410-243-7254, or go to
