Only ONE original vinyl copy of this album exists. That copy was given as a present to the band's drummer, Reinhold Stania, in 1975. It was unfortunately played too often and is therefore quite badly damaged. And to make the story even sadder, the master tapes were thrown away. Fortunately it was possible to restore (and decrackle!) the music for this reissue, though a couple of moments still don't sound perfect. Reaktor 4 was an obscure but wonderful progressive band from Germany's Ruhr Area that hardly ever played outside its hometown of Bottrop. The music is intrumental with experimental tendencies and a leading role for the flute. This CD-reissue, which includes bonus material, is an interesting item for any fanatical prog/kraut enthusiast.
