Amon Duul as opposed to Amon Duul II was one of the more maligned Krautrock groups. But then you have to bear in mind this Amon Duul were the non-musical faction of the commune, who happened to record several hours of late night jams that leaked out and got released. Chris Karrer (or was it John Wienzierl?), unsurprisingly, isn't exactly happy with those Amon Duul recordings floating about feeling that Amon Duul II is the real deal. Of course Amon Duul II made some of the finest Krautrock ever, especially Phallus Dei, Yeti, Tanz der Lemminge, and Wolf City. And even Carnival in Babylon is rather good.
There is one Amon Duul (not Amon Duul II) album not from those 1968 recording sessions, and that's Paradieswarts Duul. This was recorded at the end of 1970, released in 1971 on Ohr, and for many people's tastes, this is by far the best thing Amon Duul ever did. I guess if you can't stand the noisy bongo fests of their other albums, then this is your best bet. They go for more of a psych folk direction. A great example is "Love is Peace", complete with hippie lyrics. "Paramecanische Welt" bears more than a passing resemblance to "Sandoz In the Rain" from ADII's Yeti. I guess that's no surprise as some members ADI appeared on "Sandoz" so to return the favor, Chris Karrer and John Wienzierl appear on "Paramecanische Welt". This album does have a much cleaner sound and production. The music pretty much stays the same pace throughout, I guess it's no surprise given that this faction of Amon Duul were basically non-musicians (although no doubt, they can play better than me). The vocals aren't that great (I'm not surprised), but on the other hand, I have no problem with them. Also unsurprisingly the music loses focus at times. This album is probably not at the top of your list, but it's actually not bad, but I didn't buy this expecting the greatness of Amon Duul II at their best either.
