Pitchfork awarded 'Best New Music' to both the album and lead single "Young Hearts Spark Fire", helping to expose the band to a large audience outside of Canada.

[5] In January 2009, Japandroids signed to independent Canadian label Unfamiliar Records, who were eager to release the album, despite the band's reservations about continuing.

[5] Frustrated by label interest only after they had decided to break-up, King and Prowse reluctantly agreed to continue Japandroids temporarily, and began performing live again.

[5] In March 2009, taste-making website Pitchfork awarded the song "Young Hearts Spark Fire" a 'Best New Music' designation, instantly exposing the band to a large audience outside of Canada.

On 15 August 2010, Japandroids’ show at The Fonda Theatre in Hollywood was filmed by Last Call with Carson Daly, with their performances of "Young Hearts Spark Fire" and "Art Czars" airing during episodes on 30 September 2010, and 16 November 2010, respectively.

[16] While primarily headlining their own shows, Japandroids also supporting acts such as A Place To Bury Strangers and Health in Europe, and The Walkmen in North America.

[17][18][19] Following a handful of warm-up shows in Vancouver and an appearance at CMW in Toronto, Japandroids' first full-scale North American tour was originally scheduled to begin on 23 April 2009, in Calgary.

On the morning of 24 April 2009, King was checked into Calgary's Foothills Medical Center to undergo emergency surgery for a life-threatening perforated ulcer.

[21] Touring resumed 13 June 2009 after King's recovery with a performance at Vancouver's Music Waste festival, and continued uninterrupted through to the final show 27 October 2010 at Maxwell's in Hoboken, New Jersey.

In an interview with The Village Voice, King explained the concept, and how the Post-Nothing Tour affected their release: When we recorded our album, we had a bunch of other songs at different stages of completion.
