It’s a form of anti-TED talk.
Existing since the 1960s as a subgenre of performance, the lecture-performance or performance-lecture has its roots in the performance and conceptual art of the 1960s, and balances on the boundary between art and academia.
It’s a type of presentation that goes beyond the academic format of the lecture. Artists (not only visual or performance) use the lecture to turn it into a performance space which fuses aspects of drama and of visual and other media disciplines.
It’s hybrid nature then often expresses in borrowed hybrid elements such as storytelling, the mass media, internet, adverts, slogans, images, and technology.
The performance lecture at its best has varied functions and elements operating on multiple levels. These can form a visual rhetoric or performative actions and artistic non-sequiturs Techniques of advertising and propaganda or more straight forward education lectures and slides are used to explore the relationship between the image and the text or between consensus and the facts, or contrasting ideas or narratives.
In its artistic investigations the relationship of perception and of understanding, the audience and the performer and performance ideas can all come under scrutiny.
In that sense it is nothing like a Ted talk. It’s almost an anti-Ted Talk.
A TED talk gives you an idea and a smooth talker and tells you it’s the truth.
A performance-lecture gives you a part-idea that you have to complete, challenges you to assess its truth, your truth and the performers truth and like all good theatre can leave you activated and different from when you started.
