The article argues that period-instrument performances of early and classical music offer a genuine form of "authenticity" that is far removed from the retro nostalgia driving trends like vinyl and cassette revivals. Unlike vinyl, which the author says is objectively inferior to digital streaming despite claims of "warmth", historical instruments produce genuinely different sonic and expressive qualities to their modern equivalents, offering fresh interpretative possibilities rather than mere sentimentality. Two Proms performances this week are cited as demonstrations of how this approach can bring centuries-old music vividly into the present.

The piece traces the development of the early-music movement, crediting figures such as David Munrow, who popularised medieval and Renaissance instruments like shawms and crumhorns in the 1970s, alongside Roger Norrington, John Eliot Gardiner and Nikolaus Harnoncourt, who applied similar principles to later repertoire from the 17th to 19th centuries. It highlights concrete differences between old and new instruments, such as the quickly decaying sound of a harpsichord versus the sustained tone of a modern grand piano, and contrasts recordings of Bach's Matthew Passion by Karl Richter (1979, using full modern orchestral forces) and Paul McCreesh (2003, using a leaner period-instrument ensemble) to illustrate how these technical differences translate into markedly different emotional and musical effects.
