Hey! Thank you for good news!
Actually I found Niemen thanks to SBB (probably my favorite polish 70s band) in end of 90s, but CDs were almost impossible to get.
It is really good news Muza well reissue all of Niemen records, though i am really interested only in his prog period, and probably Idee Fixe. The others are quite a bit too electronic (and too weird) for my liking

.
I already got Green Tree Records CDs, quality reissues as well, however new Muza stuff is definitely prettier and booklet is just top notch (and has info in english). Too bad it took so many years, for example Supraphon offers excellent reissues of their stuff for many years (Modry Effekt, Progress2, Energit, Jazz Q, almost everything).
Would love to see such fine SBB reissues as well - Metal Mind reissues are pricey and kinda weird, combining old and new albums, and box is very expensive and is generally overkill for me.
