Mozart's Piano Concertos No. 20 & 21: Gulda/Abbado Reissued as Part of the Original Source Series on 180g 2LP. Pure Analogue Mix & Cut from the Original Four-Track Tapes at Emil Berliner Studios. Pressed at Optimal.

Four of Mozart's Piano Concertos have been released by Friedrich Gulda, Claudio Abbado and Wiener Philharmoniker on Deutsche Grammophon in the 1970s – all of them enjoy cult status today. Following the release of Concertos Nos. 25 and 27 as part of The Original Source Series, which met with an overwhelming response, Piano Concertos Nos. 20 and 21 are now also being reissued. To improve the audio quality, they have also been redistributed onto 2LPs.

For its 125th birthday, Deutsche Grammophon started releasing legendary recordings with highest sound standards: 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 edited the original four-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 180g vinyl records and in a deluxe gatefold edition with original covers and lyrics, the copies of this series are accompanied by additional photos and facsimiles of the recording logs and band boxes, and an article explains the exact technical background.
