The most recently opened Recording Lab at Victor was at 46 West 38th
Street, 12th floor, so it is possible that this was the actual recording
location. However, according to a time line memoir of Harry O. Sooy, in
the David Sarnoff Library, there was no mention of this event. By this
time, Sooy had been a recording technician for many years. He began work
at the E. R. Johnson Machine Works in 1898. E. R. Johnson was one of the
founders of Victor. Sooy's accounts of the recording sessions, when he
was Chief Recorder at Victor, are quite detailed so it is more likely
that the Original Dixieland Jass Band recorded in an alternate space.
Most of the music being recorded at Victor, in their New York studios in
1917, was classical and a New Orleans band playing bizarre music might
not have been entirely welcome by some. Earlier, about 1915, the cashier
at the disreputable Lamb's Café in Chicago is reported as having covered
her ears when Brown's Band From Dixieland was playing there.
In 1917, recordings could be made almost anywhere.
Often they were made in ordinary rooms in homes. The recording equipment was simply the
record player in reverse so this a good guess for the location of the
first jazz recording. The equipment was a funnel, or sometimes two
funnels, which concentrated the electric air-borne sound waves into a
diaphragm of thin glass. The glass diaphragm was linked to a cutting
stylus, or needle, pressed against a soft wax disk. The stylus carved a
groove into the wax, which recorded the ‘shape’ of the vibrating sound
energy into an audio image of the music. The original soft disk had to
be processed so that it could withstand the phonograph needle to be used
when listening to the music on a phonograph. One of the first ways to
make the wax disk stable was to coat it with shellac. In this way, the
sound image was reversed and was audible. This method of recording was
termed mechanical, since very little electricity was used in the
process. Since there was no microphone, or any other means of sound
magnification, the musicians had to be especially close to the horn
funnel that received the vibrations, and they had to be extremely loud
so that the background sounds in the room would not interfere. This is
noticeable in listening to the original record, some of which are still
in existence.
This recording opportunity turned out to be a lucky break for the band.
It was a big surprise to everyone when Livery Stable Blues became a
success, selling a million copies. However, LaRocca capitalized on it.
The Original Dixieland Jass Band was a relatively ordinary band but
LaRocca felt they should be recognized as having brought jazz into
being. He especially credited himself as the “Creator of Jazz”. This was
a cause of major disagreement and much humor as well, for the rest of
LaRocca's life. However, he never backed down from his claim.
