I was searching for Mexican son jarocho dance and found this! I'm enamoured with the soft little sounds they make with their feet, as well as the singing style. The dancer, Artemio Posadas, does a little demonstration in the middle of the video that shows the softer sounds very clearly.
...and here's one more, this time of Irish sean nos (old style) step dancers. The video had disabled embedding, but here's the link! See what you think in terms of similarities and differences between the Mexican and Irish percussive dance styles.
