Neu! (trademarked NEU! in block capitals, German: New!, pronounced [ˈnɔʏ]) was a German band formed by Klaus Dinger and Michael Rother after their split from Kraftwerk in the early 1970s. Though the band had minimal commercial success during its existence, Neu! are retrospectively considered one of the founding fathers of Krautrock and a significant influence on artists including David Bowie, Brian Eno, Iggy Pop, PiL, Joy Division, Gary Numan, Porcupine Tree, Ultravox, Simple Minds, Negativland, Stereolab, Boredoms, Radiohead, The Horrors, Electrelane, Kasabian and much of the current electronic music scene.
Klaus Dinger played drums on the first Kraftwerk LP in 1971. The following year he joined forces with Michael Rother and they formed Neu!, releasing their self-titled debut LP on German label Brain. Their music was heavily innovative and influential, melting distorted guitars with metronomic drumming, noise effects and tapes. The second LP, "Neu! 2", was released in 1973 and featured the first remix experiments, with tracks recorded at 16 and 78 rpm. The band split in 1975 after releasing their final LP, "Neu! 75". They eventually recorded more material in the 1980s. Michael Rother pursued a solo career, while Klaus Dinger went on to form La Düsseldorf. 
Neu! were highly influential on industrial, noise and experimental music.
While little known and relatively unheralded during its brief existence, the Krautrock duo Neu! cast a large shadow over later generations of musicians and served as a major influence on artists as diverse as David Bowie, Sonic Youth, Pere Ubu, Julian Cope, and Stereolab. Neu! formed in Düsseldorf, Germany, in 1971 after multi-instrumentalists Michael Rother and Klaus Dinger both split from Kraftwerk. Recorded in the space of four days with Can producer Conrad Plank, the duos self-titled debut appeared early in 1972 and quickly established their affection for minimalist melodies and lock-groove rhythms. While virtually ignored throughout the rest of the world, the album sold extremely well in West Germany, resulting in a tour with support from Guru Gurus Uli Trepte and Eberhard Krahnemann.
Rother and Dinger returned to the studio in 1973 for Neu! 2, but a shortfall of cash allowed the duo to complete only two songs, Super and Neuschnee, which they subsequently remixed at varying and disorienting speeds in order to flesh out a full-length album. After the records release, Rother joined Dieter Moebius and Joachim Roedelius of Cluster to form Harmonia, but Neu! officially reunited in 1975 to record Neu! 75. After its release, they again disbanded; Rother continued on as a solo performer, while Dinger and drummer Hans Lampe formed La Dusseldorf. In the mid-80s, Rother and Dinger re-formed yet again, although the recording sessions, titled Neu! 4, did not officially surface until 1996.
