It’s hard to believe now, but Kraftwerk were yesterday’s man-machines in 1991, when this techno-flavored remix/remodel collection was released. They hadn’t toured in close to a decade, and hadn’t released an album in five years. But by reworking many of their classic tunes in dancefloor-friendly, bass-heavy versions, they earned a new audience and reinvigorated themselves creatively. In live performance, songs like “Radioactivity” (which has an almost industrial menace here) and “Autobahn” (shaved down from 23 minutes to under 10) hew more closely to these versions than the originals. And a track like “Pocket Calculator,” originally a sub-Devo chirp-and-ping trifle, becomes a pounding, wave-your-hands-in-the-air anthem.
