A Must Have (if you like Krautrock)
Bock auf Rock is one of my favourites (listen to the different versions). Geh zum Teufel (German version of the Rolling Stones "Satisfaction") is also worth listening. I like Franz K. (wich stands for Franz Kafka). This double album contains the most popular rock songs of the band! I love it and so do my son (at least Bock auf Rock).
