"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.
 
Only a few audio recordings attest to the top-class artistic collaboration between the extraordinary pianist Emil Gilels, star conductor Eugen Jochum, and the Berlin Philharmonic. However, their joint recordings of the two Johannes Brahms piano concertos achieved cult status and are still considered unsurpassed.
