Irrlicht's atmosphericdrone music tone is similar toTangerine Dream's albumZeit, released the same year. In 2005, Schulze said, "Irrlicht still has more connections to Musique concrète than with today's electronics. I still never owned a synthesizer at the time."^[3] Schulze mainly used a broken and modified electric organ, a recording of a classical orchestra rehearsal, and a damaged amplifier to filter and alter sounds that he mixed on tape into a three-movement symphony.^[3]

Irrlicht, despite its highly unconventional nature, was originally released on thekrautrock labelOhr. Because Schulze was signed to them while a member ofTangerine Dream, the label asserted that his solo album belonged to them too;^[3] Schulze's reaction was, "I was just glad thatIrrlicht was released at all. Any other company would have probably turned me away with this record."^[3]

All tracks composed by Klaus Schulze.

• On vinyl, "Ebene" and "Gewitter" were combined into one track, listed as 29:00 in length.
• "Satz" is the German word for the musical term "movement", therefore "1. Satz" is German for "1st Movement".^[3] Translated, the titles mean:
  • 1st Movement: "Plain"
  • 2nd Movement: "Thunderstorm"
  • 3rd Movement: "Sils Maria Exile"
• The 3rd Movement "Exil Sils Maria" was recorded backwards. The recording can be heard the way it was originally recorded by being played in reverse.

• Klaus Schulze – "E-machines", organ, guitar, percussion, zither, voice, etc.
• Colloquium Musica Orchestra (4 first violins, 4 second violins, 3 violas, 8 cellos, 1 bass, 2 horns, 2 flutes, 3 oboes)^[4] – recorded as raw material then post-processed and filtered on tape.^[3]
