"The Original Source" is a series of acclaimed albums, reissued on vinyl. Berlin's renowned Emil Berliner Studios has remastered four-track recordings from the 1970s, using its own advanced, 100% pure analog (AAA) techniques to create versions of the highest possible audio quality. Compared to the original releases, the sonic benefits are outstanding: greater clarity, more detail, and improved frequency response, less noise, less distortion, less compression, and the highest possible audio quality, allowing listeners to enjoy this repertoire like never before. It took Claudio Abbado and the Boston Symphony Orchestra two sessions in February 1970, and then the recording of the team was complete. Their interpretations of Debussy's Trois nocturnes, Ravel's suite Daphnis et Chloé, and his Pavane pour une infante défunte quickly became classics.
