Claudio Abbado and the Boston Symphony Orchestra needed two sessions in February 1970 before the recording of the recorded team was ready. Their interpretation of Debussy's Trois nocturnes, Ravel's Suite Daphnis et Chloé and his Pavane pour une infante défunte became a classic.

To mark her 125th birthday, 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. They are accompanied by additional photos and facsimiles of the recording logs and tape boxes, and an article explains the exact technical background.
