I am not particularly familiar with any of the four artists involved in this unexpectedly audacious and unique album, but Celadon is definitely a kindred spirit to Important's previous iconoclastic, raga-influenced drone epics by Catherine Christer Hennix.  Charlemagne Palestine is yet another artist that unavoidably springs to mind, but favorably so: while this album is anything but derivative, Maja Ratkje and her collaborators share his willingness to take drone music into some very dissonant, uncategorizable, and cathartic territory.  Put more bluntly: Celadon is probably not for the average drone fan, as Ratkje's vocals gradually build to an almost demonic, window-rattling intensity, but it is nevertheless a bold, striking, and deceptively ferocious artistic statement that is like absolutely nothing else that I have heard.
