Ida Maria

Ida Maria gained considerable success in Norway in 2007 after winning two national competitions for unknown artists - Zoom urørt 2006 and Urørtkonkurransen 2007 - and playing successful shows at the annual Norwegian music industry festival By:Larm 2007 and 2008. Her singles "Oh My God" and "Stella" were both played regularly on Norwegian national radio station NRK P3

I tripped across Ida Maria when I was looking at related Youtube videos for Florence + The Machine one day, coming across her video for "Oh My God."  It was very much along the lines of the kind of music Florence + The Machine were making, and was a good entry into her other songs.
