You may remember Röyksopp -- the Norwegian electronica duo of Torbjørn Brundtland and Svein Berge -- from that semianimated "Poor Leno" video a few years back, the one with the adorable little zoo-kept teddy bear creature and lots of flyover shots of snowcapped Scandinavian mountains. Or maybe you were handbag shopping and arguing with your friend about whether the sorta house-y, sorta trance-y, sorta downtempo-y, vocoder-vocaled music tastefully emanating from the fancy-pants boutique's speakers was Daft Punk, Air, or Dirty Vegas, only to have the clerk tell you it was Melody A.M. , Röyksopp's 2002 debut LP. The pair is back with a new album, The Understanding, which further explores the seemingly incongruous notion of "upbeat melancholia" -- lead single "At This Moment," for example, sets a lovely blend of disco beats, bright synth burbles, and boy-girl singing against lyrics waxing wistful over a disintegrating relationship. Expect to hear material from both discs when Röyksopp arrives on Friday, July 15, to chill out Bimbo's (474-0365 or www.bimbos365club.com); as Berge explains on the band's Web site, the two find it hard to favor the new stuff over the old: "It's like trying to compare two testicles. One is not better than the other. Both are vital to the Röyksopp anatomy."
