This might be the cleanest-sounding 1928 record you've ever heard.
One quick takeaway from that happy accident -- 1928 recording technology was a lot better than you'd think it was, particularly the quality of the microphones.
It's a strange experience to come across a batch of 80- and 90-something-year-old 78s, as I did last Friday at an estate sale, and have them play almost as they did in the 1920s and early 1930s -- only on modern equipment and not wind-up acoustic gramophones.
Simply put, an electrical recording is just that: It is recorded using microphones and amplifiers feeding an electrical signal to a cutting head. Earlier "acoustical" recordings were all-mechanical -- performers played into a large horn, which moved a cutting stylus with sheer air pressure from the sound waves.
That was the reverse of the playback on an old phonograph with a large horn that amplified the vibrations from the needle moving through the record grooves.
In other words, it was . . . Viva-tonal. Indeed.
