What is mystery artist?

As an AI language model, I do not have access to information about specific, unidentified or anonymous artists, commonly referred to as "mystery artists". However, the term may refer to a variety of individuals or groups who choose to remain anonymous while creating and promoting their art. Some examples of mystery artists include the street artist Banksy, who has never revealed his/her true identity, and the musician Sia, who often obscures her face in public appearances and music videos. Mystery artists may choose to remain anonymous to maintain their privacy, avoid legal issues, make a statement about the nature of art and fame, or simply to create an enigmatic persona that enhances the appeal of their work.
