My first reactions weren't too good. Played this on home system and also noticed the more-than-several errors/glitches/pops throughout. I knew the CD was not bad, however; it's part of the master tape. Anyway, the music didn't impress me too much playing it loud on the home stereo. The next day I tried the album on headphones, and I must say this is the way to experience this. The layers of drones really come alive and "Sky" shows itself to be a haunting, beautiful gem of Grassow's archive work. So I've changed my original rating of "3" to "4". Musically it's a "5" but still a point off for the errors. Still, I highly recommend this to drone fans and Grassow collectors. Hopefully this release will pave the way for more archival reissues on this label.

Got the CD as well and i was looking very much forward to it, since it was before CDR only. But just in the first track it puts me off. There are several "noises" and digital glitches. Tested in on several CD players and it´s still the same :-( Musically i totally agree on the previous review but this errors are totally annoying.

Mathias Grassow "Sky" CDMathias Grassow's vast discography includes also many archive recordings on CDr formats and the original double CDr release of "Sky", released back in 2000, belongs to most treasured of them. Now, thanks to young Swedish label Gterma, "Sky" was revised and edited, with some new parts added, making one album on pressed CD. I think many drone fans will applaud this move of Gterma and Mathias, perfect!!! "Sky" reveals with "Opening", this deeply static drone precisely sets the mood for this breathtaking odyssey. With "Sky Part I" Mathias shifts the drone into more active heavenly realms, yet beautifully floating and sporadically evolving into denser soundwalls. Then comes almost 31 minutes long opus "Sky Part II", the sounds become immediately more massive and grandiose leading the album into the most culminating level. Everything is clear now, "King of Drones" is back at top of his mastery and "Sky Part II" is definite "creme de la creme" of this wonderfully magnificent journeying!!! More peaceful and aerial drift appears on "From Beyond", which is quite relieving after monstrous predecessor. Also "Closing" is waving on the similar territory, even if slightly more active. With "A New Beginning" Mathias moves to a new droning decade of his artistry, a truly gracious finale! 12-page booklet perfectly illustrates the beauty and immenseness of both, the sky and Mathias Grassow's phenomenal drones. Once again, big thanks to Gterma and Mathias for releasing this ultimate classic, a must have!!! Richard Gürtler (Aug 28, 2011, Bratislava, Slovakia)
