A YouTube upload, a simple error, and suddenly, Curtis Mayfield had a hit he never recorded: "Diamond in the Back." This strange case of mistaken musical identity reveals a fascinating truth: we can easily accept something as real, even when it isn't. This website explores that phenomenon in the age of AI.

Diamond in the Back is a space for us to ponder these questions, to examine the increasingly blurry line between human creation and artificial generation.
