Claudio Abbado's recording of Mahler's Fourth Symphony with the Vienna Philharmonic Orchestra, made in 1977 at the Vienna Musikverein, captivates listeners with its warm, transparent sound and great attention to detail. The orchestra's characteristic sound and Frederica von Stade's sensitive solo voice in the final movement lend the work a special lightness. Abbado's sometimes unusual tempos open up new expressive spaces and give the interpretation a special depth that makes this recording unique and highly regarded. For the first time, this recording has been remastered and cut from the original 1 inch 8 track tapes.

The audiophile vinyl series The Original Source presents outstanding recordings from the 1970s in a whole new sound quality. For this, the renowned Emil Berliner Studios have remastered and cut the original four- and eight-track tapes in 100 % analog quality (AAA) using technologies developed specifically to produce the series. The sonic differences to the original releases are considerable: greater clarity, more subtleties and improvements in frequency response, while at the same time less background noise, distortion and compression allow for an audiophile listening experience like never before.

On 180 gram vinyl records and in a deluxe gatefold edition with original covers and lyrics, the copies of this series are released limited and numbered, accompanied by additional photos and facsimiles of the recording logs and tape boxes.
