“Not only will this be the last song of the tour, this is the last song we will ever do,” Ben Gibbard announced before The Postal Service played their second rendition of “Such Great Heights” at the Lollapalooza after-party at the Metro in Chicago this past weekend.

In January, the band’s website changed to an image that read “The Postal Service 2013,” reigniting hope that the band would tour and release a long awaited second album. Their label, Sup Pop, also posted the following message:

“The band is back together, at least in 2013: The Postal Service will hit the road for a long-over due victory lap, one that will give most fans their first (and last – seriously, don’t ask) chance to see the group in person.”

The band members decided to get together for one last hurrah to celebrate the 10th anniversary of their only album Give Up with a reissue of the album including two unreleased tracks, as well as a tour.

What started out as a casual collaboration between Ben Gibbard (Death Cab for Cutie) and Jimmy Tamborello (Dntel) via the United States Postal Service (hence the name), soon came to include Jenny Lewis (Rilo Kily) and evolved into one of the most influential sounds of a generation. The Postal Service married synthetic sounds with organic ones and brought together fans across the musical landscape in a way no one could have expected.

So, now we must say goodbye to one of the best indie electro-pop outfits of our time. Watch the last performance ever below (Chicagoist) and try not to get goosebumps. Keep scrolling to listen to “A Tattered Line Of String” and “Turn Around,” the two bonus tracks from the 10 year anniversary reissue of Give Up.
