A typical busy Saturday at Russo’s Market in Watertown, just on the Newton/Watertown line. Musical performances from a series of vocalists. Guilherme Assuncao, employee of the market, stopped the crowd with his beautiful voice. People stopped, some pulled out their cameras. You can see the joy on their faces. The singer looks a little overcome by the attention and takes a deep breath before sounding out with a resounding finish! His smile tells it all.
