Engelbert and Bonde first met when they were 12 and 15 years old, respectively, and started playing together as a duo in 2004. They recorded their first album after only five months as a band, and with only three live shows to their credit. Their self-titled first album was released in January 2005 by a small Swedish indie label; it was rereleased in September 2006 by V2 Music with an additional three tracks.
Their second album, All They Ever Wanted, had its Scandinavian and Western European release in April 2008, followed by a Japanese release in 2009.
Their music is characterized by a full guitar sound supported by Engelbert's unorthodox guitar rig and myriad effects pedals, and Bonde's straightforward beats; studio releases often feature colorful percussion accents on instruments such as tambourine, woodblock, guiro, and chimes. A variety of musical styles appear in their work, from hard rock, to blues riffs, post-punk, and even gloom-pop, though lyrical themes are almost uniformly personal and slightly angsty.
