This experimental album with its electronic sighs and bleeps and atmospheric crackles is such a timeless masterpiece not because of the electronics but because of the heavenly melodies and the engaging rhythms. The whooshes, the bleeps and the disembodied voices are just the icing on the cake although they give the music an other-worldly atmosphere. The title track is mesmerising in its ebb and flow, while Radioland and Airwaves get progressively more weird. The more I listen to it, the more I think that Radio Activity is by far Kraftwerk's most varied and innovative album. What set Kraftwerk's electronics apart from most of the other synth pioneers, is the sense of classical structure that underlies the music. True, Klaus Nomi also used classic and operatic structures but he came much later. Songs like Antenna and Ohm Sweet Ohm with their beautiful melodic hooks are as accessible and addictive as their huge hit Autobahn. I recommend this album to all fans of synthesizer artists like OMD, Eurythmics, Yazoo, Suicide, Gary Numan and Sparks, to enjoy the source that most of these artists drew from to some extent.
