^Wow, yeah, now I remember "At Home He's a Tourist", great track. I'll have to give that album a listen again. It's been ages, I must have listened to it more than I recall. =)
If they give you ruled paper, write the other way.
I like Can a lot
I also like Neu!
Other krautrock is fine from time to time, earlier Kraftwerk, etc.
Other prog type stuff I like when I'm in the mood, and I tend towards the more 'out there' side of prog:
Soft Machine (their first four albums before they went all fusion jazz)
Also, Kew Rhone by Peter Blegvad and John Greaves is amazing and a must hear album
Not prog or krautrock, but other challenging, non commercial music I like:
Les Rallizes Denudés
