Kraftwerk-2 (1972)

Far removed from the classic style they would showcase in their subsequent recordings, the German group Kraftwerk, then still comprised of the duo Ralph Hütter and Florian Schneider, presented a repertoire for their second album similar to that of their debut. Utilizing classic instruments such as guitar, bass, drums, flute, organ, and violin (all expertly processed by engineer Conny Plank in the recording studios), this album displays a more abstract and irrational sound, with experimental compositions that in many cases veer into ambient, musique concrète, and sonic avant-garde. Featuring the same cover as their debut, but with the iconic green traffic cone instead of the red one, this album is a true experimental challenge that, after several listens, subtly reveals aspects of Kraftwerk's future style. Despite being one of their most underrated works, their most devoted fans consider it one of the most important albums in the entire career of this fundamental German krautrock and electronic music group.

Kraftwerk-Trans-Europe Express (1977)

Often considered a cornerstone of electronic music, Kraftwerk's sixth album is a masterpiece that has decisively influenced everything that followed, from pop and dance music to industrial sounds and new wave. "Trans-Europe Express" stands as the perfect counterpoint to the nascent technology of "Radio-Activity" (1975) and the joyful dynamism of "The Man-Machine" (1978). Composed of two distinct facets, the music here oscillates between warm, melancholic sounds and the cold, mechanical sound of electronic instruments. Although composed of a series of relatively simple pieces, it is nonetheless unforgettable, with synthesizers as the driving force and repetitive electronic rhythms reminiscent of motorik. With austere, minimalist and tremendously captivating sounds, close to gothic electronica, in this record we find wonderful compositions such as "The Hall of Mirrors", "Showroom Dummies", "Europe Endlos" or "Metal On Metal", all of them under futuristic cloaks and magnificent robotically processed voices.

Kraftwerk-Autobahn (1974)

As a result of frequent trips on the motorway that originated in Dusseldorf, the residence of the Kraftwerk components towards Cologne where the recording studio was located, in 1974 "Autobahn" was published, which made the fourth Kraftwerk album chronologically.
This album definitively marked the change of style of the band, moving away from the krautrock of the first works to be drifting towards entirely electronic sounds.
"Autobahn" was a risky experimental step that musically represented a road trip, spiced up with sounds such as the engine of a vehicle, the noise of the surrounding traffic or the sounds of the radio stations.
"Autobahn" is considered the first recording of electronic music, although there were certainly others before this one, none had the repercussion that this work had for the later development of electronic pop music.

Kraftwerk-The Man Machine (1978)

"The Man Machine" is considered one of the masterpieces of electronic music and experimentation.
With this album Kraftwerk reacted to criticism from the British specialized press that accused them of threatening conventional instruments for music developed from machines.
However and following a line in accordance with his previous works, the concept of the album revolves around a declaration of love for the machine and its positive interaction with man.
From a musical point of view, the German band have never been so inspired as in this work, which has the most beautiful and memorable melodies of their entire career.
Also in this work they moved away from the references of imitations to other conventional instruments like the violins or the choirs used in albums like "Trans Europe Express" or "Radioactivity", using exclusively electronic instruments.
The album would go on to be Kraftwerk's biggest hit as it sailed between effective commerciality and unanimous acclaim from the world press.
Russian constructivism, Italian futurism, French avant-garde, and German expressionism, were a cocktail of influences that the band knew how to transmit achieving this superb album.
