A concept album exploring themes of broadcast communications, Radio-Activity marked Kraftwerk's return to more obtuse territory, extensively utilizing static, oscillators, and even Cage-like moments of silence to approximate the sense of radio transmission; a pivotal record in the group's continuing development, the title track – the first they ever recorded in English – is their most fully realized electro-pop effort to date, while "The Voice of Energy" precipitates the robot voice so crucial to their subsequent work.

Continuing to work with Conny Plank, who once again provides a compelling job as producer and engineer, Kraftwerk went right ahead and named their new album after their two remaining members – an understandable enough move. Like the first two albums, Ralf and Florian still has not seen official re-release, for all that one can practically taste Kraftwerk's leap into the beyond on it. Given that this was the last album before the most famous lineup was formed and Autobahn was released, it's appropriate to listen to Ralf and Florian as a harbinger for the future, though perhaps all too easy. Take it on its own terms – a further investigation of electronic possibilities in a more open-ended, less constantly structured fashion than would be the case later – and Ralf and Florian becomes most enjoyable.

During the mid-'70s, Germany's Kraftwerk established the sonic blueprint followed by an extraordinary number of artists in the decades to come. From the British new romantic movement to hip-hop to techno, the group's self-described "robot pop" – hypnotically minimal, obliquely rhythmic music performed solely via electronic means – resonates in virtually every new development to impact the contemporary pop scene of the late- 20th century, and as pioneers of the electronic music form, their enduring influence cannot be overstated…

Kraftwerk is a German band formed in Düsseldorf in 1970 by Ralf Hütter and Florian Schneider. Widely considered as innovators and pioneers of electronic music, they were among the first successful acts to popularize the genre. The group began as part of West Germany's experimental krautrock scene in the early 1970s before fully embracing electronic instrumentation, including synthesizers, drum machines, and vocoders.

Minimum-Maximum is the first official live album release by Kraftwerk, released in June 2005, almost 35 years after the group gave their first live performance.

Kraftwerk's Wolfgang Flur in collaboration with U96. There are few genres in which German artists play such a central pioneering role as they do in electronic music, be it techno, electropop, trance or rave. At the frontline for many years were Kraftwerk and U96, two absolute trailblazers of this musical direction. While Kraftwerk wrote international music history mainly in the 1970s with cult albums such as Autobahn (1974), Radio-Aktivit?t (1975), Trans Europa Express (1977) and Die Mensch-Maschine (1978), U96 had a profound influence on the global pop music, rave and techno scene of the 1990s with hits such as 'Das Boot', 'Love Sees No Colour', 'Night In Motion' and 'Heaven'./quote]

Die Mensch-Maschine is closer to the sound and style that would define early new wave electro-pop - less minimalistic in its arrangements and more complex and danceable in its underlying rhythms. Like its predecessor, Trans-Europe Express, there is the feel of a divided concept album, with some songs devoted to science fiction-esque links between humans and technology, often with electronically processed vocals ("Die Roboter," "Spacelab," and the title track); others take the glamour of urbanization as their subject ("Neonlicht" and "Metropolis"). Plus, there's "Das Modell," a character sketch that falls under the latter category but takes a more cynical view of the title character's glamorous lifestyle…

Although Kraftwerk's first three albums were groundbreaking in their own right, Autobahn is where the group's hypnotic electronic pulse genuinely came into its own. The main difference between Autobahn and its predecessors is how it develops an insistent, propulsive pulse that makes the repeated rhythms and riffs of the shimmering electronic keyboards and trance-like guitars all the more hypnotizing…
