Due to the big success of The Original Source Series, on 3rd May 2024 Deutsche Grammophon will launch Batch #5, presenting four more legendary recordings. Same high standard as with the previous releases of The Original Source series: All are 4-track recordings from the 1970s, remastered by Emil Berliner Studios, using their own cutting-edge and 100% pure analogue techniques (AAA) to create versions of the highest possible audio quality.

The new batch presents much praised interpretations of the symphonic repertoire, including Karl Böhm’s iconic version of Beethoven’s “Pastoral” Symphony and Claudio Abbado’s wonderful rendition of Brahms’s 1st Symphony, both with the Wiener Philharmoniker. Daniel Barenboim and the Chicago Symphony Orchestra are heard with their exciting recording of Bruckner’s 4th Symphony, and Rafael Kubelík’s legendary collaboration with the Boston Symphony Orchestra in Bartók’s Concerto for Orchestra.

Produced on 180g virgin vinyl by Optimal, these limited and numbered releases will be issued in deluxe gatefold editions featuring the original artwork and liner notes, with additional photos and facsimiles of the recording documentation on the inner sleeve. Furthermore, each release includes a note by Rainer Maillard/EBS detailing the technical background and procedure of the Original Source Series, and an additional insert with a photo of the original tape box. Each LP comes in a protective cellophane jacket with a sticker highlighting the USPs of the series:

Pure analogue mixed & cut from the original four-track ½-inch master tapes (instead of the ¼-inch stereo copies)

Mixed by Rainer Maillard & cut by Sidney C. Meyer directly from original analogue source at Emil Berliner Studios
