DG: A brand of Deutsche Grammophon. The company was founded in 1898 by Berliner, the founder of the recording industry, and is controlled by the British Gramophone Company. In 1917 it separated from the British Gramophone Company and used the Polydor trademark. Thanks to the participation of a group of masters such as Karajan and B?hm, it rose rapidly from the 1950s and established an authoritative position in the classical music world. Conductors Furtw?ngler, Bernstein, Mravinsky, Abbado, Johum, Freejoy, Boulez, Sinopoli, Gardner, violinist Oyster Lage, Milstein, Kremer, Mutter, Perlman, Gil Shaham, pianist Horowitz (late recording), Kempf, Golda, Anda, Michelangeli, Argerich, Pollini, Zimmermann, Pires, cellist Fournier, Rostropovich, Maisky, singer Domingo, von Otter, Orfeo Chamber The band and other new and old performance elites have produced a large number of classic records under its banner. Last year, to commemorate the 100th anniversary of the company's founding, DG launched a set of mammoth "DG Centenary Special Album", with 63 CDs in 7 large boxes, collecting important recordings from various periods since the founding of DG. In 1998, the 60-CD "Chelibidak Album" was a set of records launched by DG. Archiv is also a brand of DG. It was founded in 1947 and focuses on ancient music from the Middle Ages and Baroque period. From 1974 to 1975, it launched a large-scale Bach album, with 99 LPs. Today, its well-known artists include Gardner's Solo Soloists of British Baroque Music, the Revolutionary and Romantic Orchestra, and others. In the past, many people criticized DG's recording quality for its uneven quality and harsh tone, which was not liked by Chinese people. In recent years, DG has insisted on using its 4D proprietary technology in the recording of new albums, and has achieved good results. Now, its CD sound quality has stabilized at a very high standard.

EMI Classics: formerly the British Gramophone Company and British Columbia Records founded by Berliner, the originator of the record industry. In 1931, in order to survive the Great Depression, these two rival companies merged into one and merged with some small record companies to form EMI, the largest record publishing group at the time. EMI's predecessor, the British Gramophone Company, used the brand "Master's Voice" (HMV), and the British Columbia Company's trademark was "Columbia". They were still used separately after the merger into EMI. In post-war Japan and the United States, EMI continued to use the Angel trademark until the 1990s when it was unified into EMI Classics. Due to its oldest qualifications, EMI has the largest historical recording database. Here, the most outstanding performers of all periods have left recordings, including violinists Kreisler, Adolf Busch, Jacques Thibault, Heifetz, Milstein, Szigeti, Menuhin, Ginette Never, Oistrakh, Perlman, cellists Casals, Feuermann, Dupre, Totelier; conductors Furtw?ngler, Klemperer, Karajan, Cheliby Daquet, Beauchamp, Giulini, Muti, Tenstedt, Jansons, pianist Cortot, Rubinstein, Schnabel, Ripati, Edwin Fischer, Giselle King, Solomon, Kovacevich, singer Caruso, Gilly, Chaliapin, Karas, Bjorlin, Schwarzkopf, Kanava and so on. In recent years, there have been an endless stream of newcomers, such as Korean female violinist Zhang Sarah, female cellist Zhang Hananna, conductor Simon Rattle, Wilsher-Most... The incomparable glory of the past is due to the efforts of the new generation of performers. The following has been perfectly continued.

When sorting and reprinting old records, EMI uses very mature digital processing technology. The advanced CEDAR program can reduce noise in old recordings without damaging the sound quality. Japan's Toshiba's 2088 technology is also a new technology developed in recent years. It uses 20-bit analysis power and a sampling frequency of 88.2 kHz to process master tapes, improving the timbre and dynamics of old recordings. On recently reissued old recording CDs, ART (meaning "Abbey Road Studio Technology") is a common logo, telling us that the recording on this CD has been carefully processed by Abbey Road Studio engineers. The "Great Recording Series of the Century" currently being launched by EMI is its highlight at the end of the century. The tracks and versions have been carefully selected and gathered by masters, making them highly collectible.
