This album was an early eighties compilation of their work spread over a double LP, with the later songs slightly over-represented. (The first and most progressive and raw album was fully ignored, as is so often the case.)
Hopefully the band itself needs no introduction, they managed to sustain an interesting and unique sound throughout the seventies all the way to the 1982 Nachtfahrt after which I confess I dropped out, expecting only eighties pop. Surprisingly they even made it to wikipedia-fame (but not presumably the Almanach de Gotha), though only in abridged format. Of course I would recommend hearing all the original albums especially since the earliest ones are under-represented in this compilation. Of note, I couldn't recognize the A2 track (Berliner Ring), perhaps someone could assist-- was it original for this release?
With regards to Kraan-related material, it's important to be aware of the guitarist Wolbrandt's solo work So Weit which is really just another Kraan album both in sound and artistry. Being more cohesive, I found it to be just a genuinely adorable and beautiful piece with all the happy energy and wild enthusiasm that so characterizes the band's efforts (just like the so very similar Kjol and Andy Goldner albums ex Exmagma). However, the others didn't fare so well, as I found "Alto" Pappert (saxophonist)'s albums somewhat inferior, and the bassist Hellmut Hattler's Bassball to be not worth hearing twice. Or at least so I recall.
Some of these songs should be very familiar, as the very representative instrumental Flyday from the album of the same name indicates...
