Norwegian duo Röyksopp started out wrapping broken-beats jazz warmth and rippling synthesized chill into intricate patterns. Rubbing up against acts like Boards Of Canada and Air, the group made a formidable entry into the album circuit with 2002’s Melody A.M., which matched slow-beat dirges with propulsive filter-disco house. Most of Röyksopp's stuff since—2005's The Understanding and a 2009 album called Junior—has proven more vocal-minded and driven toward songcraft, mostly for the better. Röyksopp leans toward vocal collaboration, and have done so with artists such as Karin Dreijer of The Knife and Fever Ray, Lykke Li, and Robyn. 2010's Senior is a return to the more introverted and instrumental style of the duo's roots.
