Radio art is a very broad term for auditory arts that use the radio as a form of transmission.
While these types of artistic projects can range from technical uses of sound, to more social programming like interviews and audio performances, any art that seeks to use the properties of radio for its process is often called radio or radio delivered art.
In many definitions of this kind of art, the artist is not a professional radio producer , but someone who is using radio in a new way to showcase different kinds of artwork.
Certain types of interviews can be called radio art if they have a performance art component, or are otherwise delivered as an artistic product.
These types of social performances can also be called radio art if they are part of a greater set of radio broadcasts that are universally regarded as artistic.
There’s also a category of dramatic radio based art that uses the unique venue of the radio to reach an audience in a different way.
Fans of this type of art work can look to fine arts organizations in a given nation or region of the world to find more established venues for radio art. This can also be a good resource for artists who want to become a part of the radio art community.
