Kraftwerk - Klingklang

Klingklang - Kraftwerk 2

"The nearly side-long effort "KlingKlang," which would later give the name to the band's studio and which predicts later lengthy efforts like "Autobahn," shows how the duo is still working toward its future styles. Steady beats are sometimes sped up and slowed down; more freeform performances on flute, violin, and keyboard remain present (rather than honing in on a core melody); and again, no vocals yet grace the recordings."
