"Neutronics 98 (A Tribute to Conny Plank)". Plank had died in 1987. For many years the acrimony and legal wrangling between Rother and Dinger prevented their reaching agreement over licensing arrangements to make Neu!'s music available on CD. In the ensuing vacuum, illegal and inferior-quality bootleg CDs (mastered from old vinyl records) were distributed by an outfit called Germanofon. This situation was finally resolved in 2001, when Rother and Dinger put aside their differences and entered a studio to transfer the three Neu! albums to CD, from the original master tapes (reportedly mastering each album three times). These were produced and released by Grönland Records (licensed to the Astralwerks label in the US), packaged with stickers featuring rave reviews by notable artists, including Thom Yorke.

The compilation features both new and established artists from all around the world including Oasis, Primal Scream, Kasabian, School of Seven Bells, Ciccone Youth (Sonic Youth), Holy Fuck and the young band Pets With Pets from Australia. This was to outline the enormous influence of Neu! which spans multiple decades and countries. The rights to the Neu! back catalogue are jointly owned by Rother, Dinger's estate and Plank's widow, Christa Fast. Rother worked with them to produce a box set that
