The recordings by Herbert von Karajan and the Berliner Philharmoniker are legendary - as is the interpretation of Richard Strauss' tone poem "Death and Transfiguration" and his "Four Last Songs", a reference recording with the singular soprano Gundula Janowitz, released in 1974. Since David Bowie's confession that this was one of his 25 favorite records, it even achieved cult status far beyond the boundaries of classical music. To mark its 125th anniversary, Deutsche Grammophon is releasing legendary recordings in the highest sound quality: the new 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-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. The copies of this series will be released on 180g vinyl records and in a deluxe gatefold edition with original covers and lyrics, limited and numbered, accompanied by additional photos and facsimiles of the recording logs and tape boxes, as well as an article explaining the exact technical background.
