"Northern Lights" is one of many tracks on Thank You for Today that coincidentally use seasons as metaphors for titles, alongside "Summer Years" and "Autumn Love". In the tune, Gibbard mentions Dyes Inlet, an inlet in western Washington, near Bremerton, where Gibbard grew up. In one live performance of the song, Gibbard dedicated the song to those living in Bremerton. In writing the track, Gibbard wanted to "write a song that was like a John Hughes movie that takes place in my hometown, about two people in this suburban wasteland with nothing to do who spend their time on this body of water, one pining for the other, yet both knowing that this place will be a temporary stop in a much longer life." The song features guest vocals from CHVRCHES vocalist Lauren Mayberry. Bassist Nick Harmer recalled that "She’s just got such great energy and her voice is incredible. She strolled into the studio one afternoon and just nailed it." Mayberry has since performed the song live with the band; their first time together was at the Anthem in Washington, D.C., on October 17, 2018."
"The band was originally a solo project by Gibbard, who expanded the project into a complete group upon getting a record deal.[2] They released their debut album, Something About Airplanes, in 1998. The band's fourth album, 2003's Transatlanticism, broke into the mainstream both critically and commercially; its songs were featured in various TV series and films. The band's major label debut for Atlantic Records, 2005's Plans, went platinum. Founding guitarist Chris Walla left the band in 2014 after 17 years. The band's tenth and latest studio album, Asphalt Meadows, was released on September 16, 2022. Alongside their ten full-length studio albums, the band has released four EPs, two live EPs, one live album, and one demo album."
"Ten years ago this month, Codes and Keys (the seventh Death Cab for Cutie studio record) arrived to a tepid reaction. In my case, my vinyl preorder arrived on a day before the release date, and my buddy Neil came over to my college apartment to drink beer, play video games, and listen to the record. We’d loved the sensational music video for the lead single, “You Are a Tourist”, and hoped that song was a good indication of how the other ten tracks would fare. Similarly, Gibbard had performed a solo rendition of “Codes and Keys” for NPR on just a piano and the track, despite its jaunty rhythm, had a haunting quality that teased the best of their earlier work."
