One of electronic music’s most crucial and lavish box sets, The Catalogue contains eight Kraftwerk albums remastered by founding member Ralf Hütter: Autobahn (1974), Radio-Activity (1975), Trans-Europe Express (1977), The Man-Machine (1978), Computer World (1981), Electric Cafe (aka Techno Pop, 1986), The Mix (1991), and Tour de France Soundtracks (2003). Some purists were upset with liberties taken by Hütter -- specific elements of certain songs sound sharpened, evidence of some noise reduction, and so forth -- but they are few in number and minor in effect. (The gripes were quite possibly made with the intent to prove that they know the ins and outs of these albums more than you do.) The box itself is 12 inches by 12 inches, rather hefty. The eight discs, nested in four dense foam compartments, are individually packaged in sleeves that replicate the original artwork, whether through the disc’s pouch or the slipcase in which the pouch is (tightly) housed. Each album gets its own 12-by-12 booklet with full-page images.
