Here in Guam it isn't unusual to see groups of people sitting in the shade passing a guitar around. Ukeleles are common also. Even some local rock bands set up in a beach side pavilion to rehearse.

Unfortunately whenever they have a party here they hire a DJ with amplifiers snd speakers. The music is so loud that it makes any other music impossible. I wonder that people can talk in such an environment. When I go to those parties I take my food and drink as far from the pavilion as I can get and still be in the party. I generally am not alone.

We have one band on the island that I would classify as professional folk (kinda). They draw small audiences who have no problem singing along.
