Feuer is pretty much the very first tune I wrote after I bought the Korg Wavestation back in 1992. Which goes a long way to explain why the whole track is exclusively built using Wavestation factory sounds.
The main part is "Firedance", which is a sequenced instrument that plays it's own rhythm.
This is again one of the tunes that I still like to listen to today. It has got something between Jarre and Tangerine Dream going on.
