The hiatus was brought about for several reasons including high stress derived from touring, personal differences among band members, and vocalist Daryl Palumbo's struggles with Crohn's disease.

[1] Palumbo was also beginning to write softer music that didn't fit Glassjaw's style, and started the dance-punk side project Head Automatica in 2004.

[2] During this time it was believed that Glassjaw had quietly broken up due to an extended period of inactivity, however in 2005 the band reformed and started writing and playing a handful of concerts.

Guitarist Todd Weinstock, bassist Dave Allen and drummer Larry Gorman, who were all a part of Glassjaw prior to the hiatus, had joined other projects and did not return.

Weinstock started the electropop group Men, Women & Children, and Gorman had joined Head Automatica with Palumbo.

[3][4] In 2005, Glassjaw released the digital-only EP El Mark featuring previously unreleased songs from the Worship and Tribute sessions.

Shortly after the postcard was sent out, Glassjaw simultaneously performed a concert in the United Kingdom and also released a 7" vinyl single for the song "All Good Junkies Go to Heaven" on August 8, 2010.

In support of Our Color Green (The Singles), Glassjaw underwent their first full US headlining tour in four years running from February 13 through March 26, 2011.

[32] As part of a pre-order package deal for the tour, the band offered a limited edition silk-screened poster with the purchase of a ticket.

Chris Harris of Gun Shy Assassin, and also writer for MTV and Rolling Stone, praised Daryl Palumbo's vocals on "All Good Junkies Go to Heaven" and noted that the guitars sounded "vibrant, hypnotic, and ethereal — sometimes all at the same time.

"[16] Writing about the compilation Our Color Green (The Singles) Chris Harris wrote, "no sensible person would pay for this EP when they can just download it for free," however, he continued that he was a fan of the band and that he'd "like to see [Glassjaw] make some [money].
