The three tracks on the first CD are a complete Schulze
concert in Budapest, recorded in 1982 in a huge sports arena! With the studio track 'Verblüffe sie!' (Astonish them) CD2 contains a bizarre and astonishing piece of music with its heavy beginning and soft ending. It must have been recorded by Klaus
around 1985, because it's from a PCM recording and Klaus
used that recording tool only during the mid eighties.
'Seltsam Statisch' is most likely a studio recording from around 1985. The long steady beat is kind of hypnotic. CD3: 'National Radio Waves' was found on a PCM cassette with no further inscription except for the word: 'Interessant' (interesting), while 'The Midas Touch' is nothing but a very catchy rhythm, some sounds, and a voice (certainly not Klaus
'), and again it's from the mid eighties. Both CD2 and CD3 also contain short excerpts from an interview of 1984.
