In the last 8-10 months I have been shooting people at the North Star Cafe during Tango nights ( turns out you can Tango in Portland several nights a week.) In April on a trip to Buenos Aires I shot Tango as well. On the last day in BA I stumbled upon "La Glorietta" an outdoor dance pavilion in the Belgrano area. I spent 45 minutes as people arrived and started dancing trying to get an image. ( check this link out for a group we saw playing on the street... http://www.purevolume.com/elmetodotangojazz
The last cut off this album from 2007 Paranoico Critico is Libertango. I highly recommend a listen. And Monday night I went to the Gazebo on Portland's Eastern Prom where a few Tangoesta's were dancing.
