The Aesthetics of Recording: The Production Methods and Philosophy of the Producers Behind 20th-Century Masterpieces

Recording technology has not merely served as a means of reproduction; it has quietly but decisively transformed the very nature of music itself. We are now in the midst of an acoustic experience that was once unimaginable. The reconstruction of space through multi-channel audio, the precision of frequencies extended beyond the audible range, and even the perception of sound reorganized by AI—these are not just technical advancements, but nothing less than a redefinition of the act of 'listening' itself.

These developments have provided music producers with new methodologies and countless options. At the same time, however, they raise a fundamental question: no matter how sophisticated our tools become, what are we trying to depict through sound, and where are the underlying aesthetics and philosophies heading?

Looking back at history, we realize that the contours of the answer are not unique to the modern era. Rather, the archetypes of the thinking that supports today's music production are already alive in the work of the classical music producers who were active in the 20th century.

In this article, we will shed light on the practices of these masters and quietly reflect on the essence and potential of music production in the coming AI era.

In the 20th century, the emergence and dramatic evolution of recording technology brought about an 'ontological shift' that fundamentally overturned the nature of music as an art form. Until then, music was a 'one-time phenomenon' that could only be enjoyed by those sharing a specific time and space, but recording technology fixed it into a 'storable and ownable object.' This historical transformation was not merely the acquisition of a means of recording; it triggered a profound paradigm shift regarding the authenticity of music.

At one extreme were the guardians of 'uniqueness,' represented by Sergiu Celibidache. For them, music was a 'phenomenological experience' in which sound, human consciousness, and space were integrated, and recordings were nothing more than 'canned' music that killed its soul. At the other extreme were those like Glenn Gould and Herbert von Karajan, who actively utilized recording technology to pursue 'constructed perfection.' They were convinced that the truth of music did not lie in a faithful record of a performance, but rather in the embodiment of an ideal image through technology.

In this article, we will conduct a comparative analysis of three major 20th-century producers who embodied this 'construction of perfection' with their own unique philosophies: Walter Legge, John Culshaw, and Thomas Frost. They were not merely supervisors of recording engineering; they were technical architects who highly harmonized technology, psychology, and commercial strategy to design 'immortal sounds' that were unattainable in live performance. Tracing their footsteps is nothing less than gaining deep insight into the state of music production in the modern AI era.
