Throughout their career, Kraftwerk have pushed the limits of music technology with some notable innovations, such as home-made instruments and custom-built devices. The group has always perceived their Kling Klang Studio as a complex music instrument, as well as a sound laboratory; Florian Schneider in particular developed a fascination with music technology, with the result that the technical aspects of sound generation and recording gradually became his main fields of activity within the band. Alexei Monroe called Kraftwerk the "first successful artists to incorporate representations of industrial sounds into non-academic electronic music".
