This is what the Microsoft site tells us about the dancers

Evan and Michele are passionate about Argentine tango. They have been dancing, teaching, and performing together for six years, and in that time have developed a reputation for excellence in all three fields. They are obsessive about tango dancing and travel frequently to Argentina and other tango communities throughout the world.

Michele has been dancing all her life and teaching partner dancing for over 12 years. She now teaches dance full-time, specializing in Argentine tango, salsa, and West Coast swing. She is also a prolific producer of tango performances.

Evan is a physicist, inventor, and software entrepreneur. He draws heavily on his scientific background to lend a unique analytical perspective to all his classes, emphasizing the fundamental physical principles underlying the dance. Together, Evan and Michele continue to strive to express the endless beauty, sensuality, strength, and passion of the tango.
