The version of Iowa on the vinyl here DOES NOT feature the long, movie-style intro. I remember being incredibly disappointed the first time I heard the rendition in the YouTube video here. I felt like, "What the heck? Why leave that cool intro off of the vinyl release?"
Regardless, Iowa is a cool bit of acid trance/techno---bouncy, bubbly, and quite groovy.
Schattenfeuer is less interesting, and I must point out something. I have no problem with an artist remixing or even recycling melodies, percussion, or other components from one track in later material, but it's worthy of note that Schatenfeuer sounds very similar to Human Chill and Aramis, which in turn is IDENTICAL to his Remix of Acidious (Aramis, that is). Listen to all those tracks, you'll hear what I mean.
