anyway, back to the music
this is the transition between cuban danzón and the modern mambo. unlike the excitement of pérez prado, this is slower and mellow, with flute (arcaño was a flutist). the legendary cachao came up through arcaño’s orchestra. pérez prado later heard this, added his sound, and shook the world.
the danzón started as XIX century european music that got progressively africanized and you can hear some of that here
