Klaus continued experimenting with organs and tape machines in his bedroom which had been furnished as a small studio. After he got a contract with Rolf-Ulrich Kaiser's recordlabel 'Ohr' (the leading label for progressive music at that time), he recorded his first solo album, 'Irrlicht - Eine quadrophonische Symphonie für Orchester und E-Maschinen'.

Schulze's equipment: a 4-track Telefunken taperecorder, an Echo-Mini and the microphone of a Philips cassetterecorder. Because the microphone couldn't be plugged into the taperecorder, Schulze used the Echo-Mini as a pre-amp and taped with this one microphone the entire orchestra. The result was rather flat, but Schulze told the not so pleased musicians it SHOULD sound that way. He had to promise not to mention the name of the orchestra...

Track 3 "Satz: Exil Sils Maria" is played backwards...
KS: "It was by accident. After listening I removed the tape and loaded another one. The next day I wanted to listen to it again and loaded the tape, not knowing that it was playing backwards... I thought: that sounds funny! And then I noticed "Tail Out" (backwards)... Then I said: doesn't matter, leave it this way."

The "Ohr" release of "Irrlicht" contained a leaflet in LP-cover size with a chart on which KS explained the way of creating the album ("Music is aesthetisized frequency").
