Music that falls asleep and sings, that consists of new blood, of speaking gestures, an unknown scent, a bird that does not sleep; music from church windows, a swirl of complementary colors, a theological rainbow". This personal definition by Olivier Messiaen refers to both the purely musical and the extra-musical qualities that he demands of himself and ascribes to his works. It also serves as a brief summary of one of the most important works Messiaen created in his first major creative period. Mixed and edited from the original 8-track tapes, this edition offers a breathtaking listening experience of the highest analog sound quality. The audiophile vinyl series The Original Source presents outstanding recordings from the 1970s in a completely new sound quality. The renowned Emil Berliner Studios have remastered and edited the original four- and eight-track tapes in 100% analog quality (AAA) using technologies specially developed for the production of the series. The sonic differences to the original releases are considerable: greater clarity, more subtleties and improvements in the frequency response, as well as less background noise, distortion and compression make for an audiophile listening experience like never before. Released on 180g vinyl records and in a deluxe gatefold edition with original covers and lyrics, the copies in this series are limited and numbered, accompanied by additional photos and facsimiles of the recording logs and band boxes.
