The band Valdimar was founded in 2009 when Valdimar Guðmundsson and Ásgeir Aðalsteinsson started writing songs together in Ásgeir's apartment. Guðlaugur Guðmundsson, Þorvaldur Halldórsson, Kristinn Evertsson and Högni Þorsteinsson gradually joined in to render it a 6-member band. When performing live, a small brass section most often supports the band. Their music builds up from being soft and intimate to an exciting hair-raising, heart-stirring energy, often with all members on stage playing full blast, making their live performances an unforgettable
The sound of their music can be described as an electro indie mix. The band released their debut album Undraland (Wonderland) in 2010 with critical acclaim and commercial success. Four singles that were released from the album reached the Top 10, including their biggest hit "Yfirgefinn", one of the most played
songs of 2011 in Iceland. They followed Undraland by the album Um stund (For a While) released in October 2012, and it acclaimed big success as well, and was nominated as the album of the year at the Icelandic Music Awards. The album contained three big radio hits; "Beðið Eftir Skömminni", "Sýn" and "Yfir Borgina". Valdimar released their latest album late October 2014, Batnar útsýnið (The Scenery Gets Better).
