By way of an introduction; what is electro swing music?
According to Wiki; "Electro swing, or swing house music, is a music genre that combines the influence of vintage or modern swing and jazz mixed with house, hip hop, and EDM. Successful examples of the genre create a modern and dance-floor focused sound that is more readily accessible to the modern ear, but that also retains the energetic excitement of live brass and early swing recordings. Electro swing groups typically include singers, musicians playing traditional jazz instruments (e.g. trumpet, trombone, clarinet, saxophone) and at least one DJ."
And, as mentioned at the end of the above video, one of the most popular exponents are Caravan Palace.
Zoé Colotis seems to have unlimited energy to be able to sing and dance the way she does and in the final video the dance choreography and microphone handover is brilliantly executed (you may need to watch it more than once to see it!)
