John Legend's got a lot on his plate! The new father also recently spent time overseeing the music for WGN America’s Underground, which follows a group of slaves who band together to fight for their lives, families, future and freedom.

It’s the first time the 37-year-old GRAMMY winner was deeply ingrained in the behind-the-scenes machinations of a TV show. In ETonline’s exclusive look at the recording process behind the Underground theme song, one of the featurettes included on the show’s season one DVD, we catch a rare glimpse of Legend working his magic on the boards.

“Me curating the music for this show is actually different than anything I’ve ever done before,” Legend, who is an executive producer on Underground, says in the clip. “This is the first time I’ve done something of this nature for either TV or film, and I’m excited to do it with such an important show.”

Earlier this year, the singer spoke to ET about the importance of Underground’s place in television.

“I think some people are wary of slave stories in film and TV because it reminds of us a really dark part of American history,” Legend said. “But what this show did that a lot of those stories don’t do is really provide heroes for us -- and action, and adventure, and suspense, and intrigue. And I thought it was a really unique way to approach this really difficult part of American history.”
