Kraftwerk's 1974 masterpiece Autobahn made some serious noise in the experimental electronic music scene of the early 1970's. The album was a bold transition from their earlier Krautrock dabblings found in Kraftwerk 1, Kraftwerk 2, and the aptly titled Ralf und Florian release but it wasn't the first time that its type of music was achieved, nor was it the first time a concept of it's kind appeared in music. It was however, certainly different to see a full group of German men in a band sans rock instruments (but rather homemade electronic gear) doing so well.
My favorite Kraftwerk records remain Autobahn, Trans-Europe Express, and The Man Machine. There is a European utilitarian feel to the latter two, but they soon moved on to embrace the futuristic theme that many other bands of the time would also attempt. Some of the group's work into the 80's and beyond became unbearable (the popular competitive sound of other cringe-worthy 80's groups could take the blame for this too). Following some mediocre Kraftwerk releases came the expected remixing and repackaging of their mid-period hits.
My friend recently pointed out the new cover art on the most recent  pressing of Trans-Europe Express. I'm sure there is an explanation for the decision to put out a version of the album that looks like this, but I think it's pretty bad. Is this just an unsuccessful minimalist piece by former Kraftwerker/group artist Emil Schult, or a modern-day outsider's interpretation of the epic album? It just plain lacks - Not just the new school image of the TEE, but the separation of the double line Title/Artist found on almost all previous versions. Most notably, the division of "Trans-Europe Express" and "Kraftwerk" found in the updated cover's layout seems eerily symbolic.
