Unlike Bretonne (my edition had 20 songs) is my feeling the recording quality significantly better. In Bretonne in some soft passages could be heard clear noise. For 2 songs the bass pretty lousy (polterig) was matched. And at 2 other bass was for this very quiet songs somewhat exaggerated (but is also a matter of taste).
In Bretonne I knew several songs already and found it not so great implemented (again a matter of taste).
With O Filles De L'eau I knew absolutely no song.
But far away from the local Mainstreamgeleier on the radio, it is times to hear something else like an oasis. Some songs remind again Bretonne, at least in the bretonnischer and French on the Bretonne CD. If I heard correctly, also a song in English is.
But Partly me is the rhythm in some passages a little to "Mainstreaming". Sounds like there's a Rhytmuscomputer is partially used, but I did not exactly know.
Overall, however, a successful work. Opposite the Bretonne so have the impression that Bretonne yet somehow the "experimental stage" and puts O Filles De L'eau then be built on more perfect work (but is also once again a matter of taste).
No matter of taste with mE but the sound quality and significantly during mE. Here all the songs are well received roughly the same, at Bretonne the quality was in my opinion but varies depending on the song of is not at all to very good (at least for the Ausagbe with 20 songs).
With O Filles De L'eau, the sound quality is consistently about the same in good - very good.
And the matter of taste: you can in the German edition all songs 30 sec (?). listen long. Otherwise, there are also still youtube where you can sometimes songs can listen to before buying.
And at the price issue: I have the output from Austrian Empire, which also gives it here at Amazon. Find a bit cumbersome, but worth the search, because the costs a few Talerchen less and as I see it, the same songs are on it.
