WATCH: Jonas Brothers Explain How New Song Is ‘Quintessential’ JoBros

The Jonas Brothers are doubling down on the nostalgia, not just revamping their Burnin' Up tour this fall but also the sound on their latest single.

Kevin , Joe and Nick Jonas spoke with On Air with Ryan Seacrest on Thursday (August 27) ahead of the release of their new song "Listen When Sad," out on Friday. When Seacrest asked whether the "nostalgic tones and textures" in the track were reminiscent of the group's earlier catalog from the 2000s, the trio shared some insight into their inspiration.

"We wanted to tap back in to that early sound, our breakthrough album in '07...," Nick said of the song's "nostalgic feel." "That time in our lives when everything was new and exciting and we were writing about things that were happening to us in real time."
