Death Cab for Cutie would go on to enormous popularity and release records for years to come, but Gibbard's itch to work solo continued. Between 1999 and 2002, he worked on several solo releases under the name ¡All-Time Quarterback! Collaboration became standard for Gibbard early on as well. In addition to joining friends Pedro the Lion as a bassist for one tour, Gibbard has collaborated in some form or another with the Long Winters, Jenny Lewis, Jay Farrar, Styrofoam, Andrew Kenny of American Analog Set, and others. Perhaps his most fruitful collaboration came in the form of adding guest vocals to the Dntel song "(This Is) The Dream of Evan and Chan" on the 2001 album Life Is Full of Possibilities.
From that meeting, Gibbard began trading sound files with Dntel beatmaker Jimmy Tamborello for what would become the immensely popular project known as the Postal Service, thusly titled because the two would send each other song ideas through the mail. The Postal Service's 2003 debut, Give Up, was well received critically as well as in terms of sales, going gold in two countries. Gibbard married actress/singer Zooey Deschanel in September of 2009 and the couple remained together for two years before divorcing in the fall of 2011.
In 2012 Gibbard issued Former Lives, the first collection of songs under his own name. Two years later he supplied the score to the romantic comedy film The Laggies, and he returned to Death Cab for Cutie for 2015's Kintsugi, which earned a Grammy nomination for Best Rock Album. In 2017 he delivered Bandwagonesque, a reworking of Teenage Fanclub's breakthrough 1991 album of the same name. ~ Fred Thomas, Rovi
