The Godfathers of Glitch and the Kings of Kling-Klang come out of seclusion with a double live CD culled from various concerts on their 2004 tour. Minimum-Maximum is essentially a greatest-hits album with an audience applauding and occasionally shouting. Without them, of course, you'd never know the album was live, since Kraftwerk is the band that put the programming in pop music. Not much has changed with them since the 1980s. They're still wired to the same sonic circuitry as on Electric Café in 1986, sculpting glistening electro-soundscapes that pulse but never quite groove. And they still sing in that flat, German-accented English and French with Speak and Spell electro-voices. But rather than sound dated, this has a timeless charm, especially since Kraftwerk are among the few Kraut rock groups with a sense of humor. With only two studio albums in the last 20 years, you have to give them credit for not caving in to current electronica and techno trends--Kraftwerk remain resolutely electronic. Even their samples sound synthesized. But also give them credit for some of the most relentlessly glistening electronic music ever crafted, and a sound that remains surprisingly pure. All the hits are here, from "Autobahn" to "Tour de France," but nicely buffed to a high chrome finish. --John Diliberto
