Since 1999 the Norwegian duo of Dag-Åre Haugan and Espen Sommer Eide—who work together as Alog—has made some of the hardest-to-pin-down collage-style music I’ve ever heard. I’ve never been too sure about what instruments they play—album credits are scant—but whatever they’re using, they command a seemingly huge catalog of sounds, which they combine into beguiling songlike constructions. The group’s fifth and latest album, Unemployed (Rune Grammofon), is the most complex and satisfying one yet; the CD version, which I have, runs 75 minutes, and a limited-edition four-LP version is twice as long.
