Well that was extended version of Angels really not very exciting; it was hardly what one "Extended" calls (... wnigstens for me). There was only one part near the end of only a few seconds long felt. The rest was exactly what you can find with Sehnsuht or normal single angel.
But what was really exciting was the songs "Wild Wine" and "fire wheels." They both are exclusive to this single and they are absolutely amazing. In America, this single was very expensive to buy, and yet every penny worth. Both unfortunately are so worth the effort because they are so old, and you have exactly what you expect from Rammstein songs: lyrics with double, even triple meanings and captivating imagery, and of course, a good tune that it brings together all. Your age also makes them interesant because they give a glimpse of the process unit. They are both demo versions, so it's possible that it even before heartache were made. I know not sure it's just a theory, based on the text and the quality of the recording.
This single is a way for Rammstein fans to travel back in time basically.
