S&D: Popol Vuh + krautrock etc

As I've recently been getting more into krautrock, so when I saw a list on amazon's listmania dedicated to krautrock, i clicked for suggestions of new stuff to hear. somewhere down the list, i saw a group called popol vuh that i had never heard mentioned in any conversations concerning krautrock though i have admittedly had very few. the impression that i got was that they did a lot of soundtracks for W. Herzog. Is that what I can expect? I mean I liked aguirre, the wrath of god and all but I wasn't particularly struck by the sdtk--if anything I thought it was a little cheesy.
So were popul vuh more about influence in electronic music, or should I check out some of their stuff? allmusic recommended Einsjager $ siebenjager, but i'd like to hear your opinions.

On a side note, I've been getting really into Neu's self titled cd (it's the best cd i've been exposed to this year), as well as Can's tago, ege, monster movie, Kraftwerk, Amon Duul II's Tanz der Lemminge and some other stuff. Further recommendations would be appreciated.

THANK YOU HAPPY HOLIDAYS
