From "København, Kalundborg og" (directed by Ludvig Brandstrup, 1933-34)
The synced audio is sourced from the Danish-based label Storyville Records' compilation album "Louis Armstrong in Scandinavia", which is a tad bit clearer than most available versions as you can hear some sounds clearly like the drummer brushing and Armstrong's sibilances. (Headphones required!!!) I assume this must be from Gösta Hägglöf's original recordings as he was credited as a producer of these recordings in the Scandinavia compilation, and that raising the higher frequencies in the optical soundtrack would barely if not, never reveal the less heard instruments like cymbals. The compilation also fades out tracks abruptly, in which I took the liberty of replacing the silence with the muddy soundtrack of an audience cheering for continuity.
The source video was a bit faster than the recorded audio and I had to slow it down to fit the 24 fps constraint.
