[2][3] The band's sound has been described as a blend of "punk, pop, and electronically induced dance rock".

After writing songs together for three years for their respective solo albums (which were never produced), Boyd and Hansen realized they had a group forming.

In 2009, the duo sent two of their songs ("Stress" and "Money") in to the Danish National Radio P3's Karriere Kanonen ("Career Cannon") competition.

The band served as the opening act for Pink during her The Truth About Love Tour at select dates until 6 November 2013.

They opened for Fall Out Boy along with The Pretty Reckless for the European leg of the Save Rock and Roll tour in 2014.

In April 2015, the band recorded their hit "Everywhere I Go" in Simlish, a made-up language, for the game The Sims 4, bringing them more popularity to a different demographic.

[14] In October the band joined Andrew McMahon with special guests The Griswolds, as well as fellow DCD2 artist LOLO on 'The Wilderness Politics Tour'.

They posted on Facebook that the new album would focus on life after touring and growing more successful, as well as describing the task of reinventing themselves through the tight bonds that they developed as bandmates over the years.

The band announced on 18 October 2019 that their fifth studio album, An Invitation to an Alternate Reality, would be released on 1 November 2019.
