Hej Matematik

Hej Matematik is a Danish pop band, consisting of the Aqua-member Søren Rasted and his nephew Nicolaj Rasted. They did well on the Danish charts and their debut album was being marketed as "an intelligent pop record" which is most likely a reference to the songs' equivocal lyrics and atmosphere commenting on urban lifestyle. They won Danish Hit of the Year with the single Walkmand at Zulu Awards 2009 - an annual award-ceremony held by Denmark's largest commercial television station TV 2.

In November 2nd, 2009, Hej Matematik released Party I Provinsen, the lead single of their forthcoming second album. The album has been released in Denmark on January 25th, 2010, under the title "Alt Går Op I 6".

Søren Rasted together with Lene Nystrøm, René Dif and Claus Norréen started the Danish success band Aqua.

Hej Matematik had in the past a dispute with well known band R.E.M. These pretended the video Hej Matematik - Walkmand is too close of R.E.M. - Supernatural Superserious. As a consequence they contacted YouTube and asked them to block the video of the Danish band.
