Parks and Recreation was full of relatable characters, and one that became an instant fan favorite was Ron Swanson, who secretly played at jazz bars under the identity of Duke Silver. Parks and Recreation premiered on NBC in 2009 and came to an end in 2015 after seven seasons and a lot of ups and downs in the social, professional, and personal lives of the characters.

Parks and Rec followed Leslie Knope (Amy Poehler), a perky bureaucrat in the Parks and Recreation Department in the fictional town of Pawnee, Indiana, and her coworkers and friends. One of the characters that resonated the most with the audience was Ron Swanson (Nick Offerman), director of the Parks department who was best known for his deadpan personality and for showing no interest in the lives of his co-workers (although deep inside he did care for them). Ron also had a big secret: an alter-ego named Duke Silver.

Duke Silver was a saxophonist and leader of the jazz group The Duke Silver Trio. He performed at Cozy’s Bar in Eagleton on the second Thursday of every month, and had a pretty solid fanbase that consisted mainly of middle-aged women. It’s unclear when Ron started performing as Duke Silver but it makes sense that he kept it a secret for years: Ron was known for going to extremes to keep all information about him private, so it’s only natural that he did the same with his music career. Duke Silver released a total of three albums: Smooth as Silver in 2004, Hi-Ho, Duke! in 2007, and Memories...of Now in 2009.

Parks and Rec - Ron as Duke Silver performing on stage

Ron kept his alter-ego a secret from his coworkers for years... or that’s what he thought. In Parks & Rec season 2, Mark Brendanawicz told Tom to go to Cozy’s Bar as he was trying to find some dirt on Ron. Later, Ron discovered that Tom had a green card marriage, so they agreed to keep each other’s secret. April revealed to Ron that she had known his secret since she met him because her mom was a Duke Silver fan. Finally, in season 6’s finale, Ron revealed his identity during The Unity Concert after being encouraged by his wife, Diane, to perform. It’s unknown what happened with Duke’s music career after Parks and Rec ended, but with Ron accepting the job as superintendent at the Pawnee National Park, Duke Silver was probably left behind.

Duke Silver was one of the best parts of Ron’s character, as many viewers wouldn’t have expected him to have an alter-ego that plays jazz at bars, but at same time it was on-brand, as he was more complex than most people think. Duke Silver might have ended after The Unity Concert, but Parks and Recreation gave the audience the chance to enjoy some of his soft tunes.
