Large areas of Green Lake Park are occupied by singing, dancing and instrumental groups. Some are clearly well-rehearsed and enjoy having an audience [see JD enjoying one, below]. Others are more amateur, inclusive and spontaneous. One of the largest consisted of a tape-player hanging from a tree playing a simple ethnic minority tune, surrounded by 50-60 people in a circle, doing simple dance steps to the rhythm. As gaps appeared in the circle, passers-by would join for a few minutes before moving on. Even JD had a try. It's clearly popular as a social and exercising activity, yet not one of the dancers showed even the slightest smile. Odd.
So, ethnic music, traditional Chinese music, musicians practising alone, disco music, warbling soloists, 10 piece bands, buskers - all doing their thing within eyesight and earshot of each other. Like a free musical smorgasbord. Very strange, yet immensely uplifting.
