It wasn't the average traffic stop on the Baltimore Beltway Tuesday morning.

Maryland state troopers noticed a man playing a drum kit on the shoulder of the Interstate 695 inner loop, between Windsor Mill Road and Security Boulevard, around 10:30 a.m., a spokeswoman said.

He told state police he had run out of gas and decided to set up and practice until assistance arrived. A State Highway Administration truck stopped and helped him refill his tank

The drummer was not cited and continued on his way, she said. Police did not identify him.
