PHILADELPHIA (CBS) — Some guys with demanding day jobs are finding time to make music in their free time.

Radiologists and an air traffic controller by day. Progressive rockers by night. That’s the story of the Philadelphia-based band Shadow Merchant.

“Back when I was in medical school,” says co-founder, guitarist and radiologist Sean Reiter, “the dean of our medical school, who was an OB-GYN, used to refer to radiologists pejoratively as shadow merchants.”

A good name for a band, he thought.

“We do have busy day jobs and families, and it’s tough,” Reiter says. “So we have one night a week that we practice together.”

And progressive rock fits air traffic controller and keyboard player Don Henney’s style.

“You see a lot of 3-D, a lot of three dimensional stuff,” Henney says. “So there’s a lot of projection where planes are going to be. And it’s complicated. And I tend to look for that in music.”

Shadow Merchant is out with their debut CD entitled ‘The Tunnel.’
