I had an opportunity to meet Daniela Borgialli, a wonderful teacher of Argentine tango, while she was here in Phoenix for a few days. I observed one of her advanced classes and she's a magical teacher. Daniela was so generous with her time while I was writing my initial paper about tango a year ago, and we spent many hours on Skype between Phoenix and her home in Berlin. I'll be talking with Daniela again next week and can foresee collaboration in our future....
