This was Amon Düül II's first album, after they were formed from the respectively called 'Amon Düül', a free-form underground band (or more a gathering) of young people in Germany that played improvisational pieces.
Amon Düül II was founded to produce constructed music instead of improvisational pieces by members of the Amon Düül gathering.
As another review says, the album is indeed, rather difficult to listen to, taking into consideration the extremely poor 'mastering'.
My biggest issue with the product (and not the music itself) is that it comes in a paper sleeve, which makes the vinyl record EXTREMELY dirty. When I unwrapped the plastic wrapping, I took the vinyl out and there was immediately so much dirt and unwanted dust on the vinyl, I played it straight away, and the amount of cracks and pops could be heard through my respectable setup.
ReVisited's other re-releases (such as Amon Düül II's Yeti double LP) come in separate paper LP covers and are the kind you would see actually being used to protect vinyl records. The quality upon unpackaging the product is such a substantial difference.
If you purchase this re-release, be prepared to clean the record after each play if you're going to put it back in the original paper sleeve, because it will get dirty. I would suggest purchasing the plastic, anti-static LP sleeves and then slotting that inside of the original paper sleeve to protect the record.
Oh, and the track listing is laid out incorrectly on this reproduction. The A side contains the 20 minute 'Phallus Dei', whereas, on original versions, this was on the B side.
All of the other tracks on the album are now on the 'B' side.
Listening to the wonderful 'Phallus Dei' straight away is rather out-of-place, as it does not really fit in the way it should.
Awesome album worth collecting for any fan of progressive rock or Krautrock, absolutely disastrous reprint from Revisited (even though their other products are fine).
Buy a dust cloth or a brush with this record if you do not previously own one.
