12345678 3-D is a single-disc distillation of Kraftwerk's Grammy-winning 2017 box set 3-D: The Catalogue, which contained full reproductions of their studio albums from Autobahn to Tour de France in the arrangements devised for their 3-D tours since 2012. Since that box set contained no crowd noise, or barely anything else that suggests a live performance, this disc essentially amounts to an album of re-recorded hits (and a few interludes). The tracks are often much shorter than they appear on the original albums, as they were arranged to fit the flow of the concerts. Essentially, the disc seems like a handy souvenir for anyone who has attended one of the group's concerts but isn't interested in springing for the full box set. It could also work as a passable sampler for anyone new to the group, since a single-disc Kraftwerk best-of has surprisingly never remained in print. Of course, most people interested in Kraftwerk are likely to start with their original albums anyway, so this disc isn't exactly essential.
