I believe the instrument the gentleman is playing is called an "erhu," which is a two-stringed instrument sometimes called a "Chinese Violin."
I came across this musician in Boston Public Garden, late in the afternoon of March 11, 2020.
I placed a couple of dollars in his jar and enquired via sign language and facial expression whether I could have permission to take his photo. He obliged.
I used my Holga 120N equipped with Arista EDU 400 film. I processed the film in Rodinal developer.
People ask me all the time,...where can you buy film now? I get the Arista film from Freestyle Photo Supply in Los Angeles. They also sell Kodak, Fuji, Fomapan, Cinestill, Ilford and other films. If you have a Samy's Camera near you they have film. Your local independent camera shop probably sells film. By mail order you can get film from numerous sources, including the aforementioned Freestyle (https://www.freestylephoto.biz/)
as well as the Film Photography Project Store (https://filmphotographystore.com/) and other photographic outlets.
