i think i've tried having this argument before, but i reckon Landed and even Flow Motion now you mention it are better than Tago Mago for instance. They are certainly my favs anyway.
I'm fairly orthodox when it comes to Can ( Soundtracks and Tago Mago are my faves ) but without the Virgin releases to prime my interest i doubt very much if i'd have listened to Tago Mago when i did ( about 1980 i'd guess, otherwise i might have had to have waited until the publication of KRS to give me the heads up ! )
