Baron Bodissey:

The durable scratch-resistent hi-fi record emerged just as CDs made it a thing of the past.

The hi-fi LP was first sold in 1948. The stereo LP was first sold in 1958. The CD was first sold in 1982 (Europe) or 1983 (the United States). The gap is quite a long time relative to the length of time that sound has been recorded.

Bach, whose Baroque technique was by far the finest, but whose works were produced just as musical taste and instrument technology were pushing Baroque music into the dustbin of history.

Bach was never pushed into the dustbin of history. His works for larger ensembles, e.g., cantatas and oratorios, were largely unplayed from Bach’s death in 1750 until Mendelssohn conducted a performance of the St. Matthew Passion in 1829, but his keyboard works continued to be widely played during that period. Other Baroque composers, of course, were largely unheard until the 1960s.

Minor quibbles on my part, however. You raise a thought-provoking point with wide validity.
