This week on Under the Radar with Callie Crossley:

Banksy, the British artist who has stayed out of public view since the 1990s, is arguably the most famous and lucrative street artist in the world. A selection of his work is now on display in Cambridge as part of a traveling exhibition called “The Art of Banksy.” Exhibitors independently sourced more than 100 pieces of Banksy's outdoor and indoor artwork to include.

Banksy’s artistic activism, or “artivism,” and his global influence got us thinking about Greater Boston’s art activism scene. Who are the street artists transforming our city walls and spaces? And how do they interpret issues through their art?

Guests:

Abigail Satinsky, curator and head of public engagement at Tufts University Art Galleries and program director of the Collective Futures Fund.

Cedric Douglas, street artist and designer who has created artwork around Boston for more than two decades. He is also the founder and creative director of the Up Truck.

Sneha Shrestha aka IMAGINE, a Nepali artist, educator and social entrepreneur who meshes the Nepali alphabet with the Boston graffiti scene. She is also the arts program manager at the South Asia Institute at Harvard.
