'Teardrop Windows' is taken from the new album Former Lives, which will be released on November 12.
The song was written as a tribute to Seattle's Smith Tower, the oldest skyscraper in the city.
Gibbard said of the song: "To me, it represents the things we take for granted when something newer, bigger and flashier comes into our lives."
The songwriter also revealed the 12-song tracklist for the album. Speaking about the LP's themes, he said: "These songs span eight years, three relationships, living in two different places, drinking then not drinking.
"That's not meant to be cagey, it's the absolute truth. With these songs, there's going to be a lot of time between when they were written and when people are finally going to hear them."
He added that the album does not mark the end of his band Death Cab for Cutie, saying: "Creatively, I'm really cleaning slate.
"I'm doubtful I'll have another solo album for another 10 years because the health of Death Cab for Cutie has never been better.
"It's exciting because for the first time in a long while, I'm starting from scratch as a songwriter - there's no backlog of material to pilfer ideas from. It's freeing and terrifying. But mostly freeing!"
