I've returned from Oaxaca with a couple of projects...still very much work-in-progress, but should be uploaded on my website in a few weeks. The above photograph is a 'sneak preview' of one of them.
Oaxaca's main square, the zocalo, is a wonderful place to relax, have a meal or good coffee, watch the world go by and hear some street music. It's admirable of the city's municipality to stage free performances of Oaxacan regional dances as well as music by the local brass band every weekend in the square. The audiences are mostly of Oaxacans, but some tourists also stop to enjoy the spectacle.
If you haven't been to Oaxaca yet, trust me...put it on your list. I had heard that David Alan Harvey was in the city with his students, but regrettably our paths didn't cross.
