Public Enemy, also known as PE, are a seminal hip hop group known for their politically charged lyrics and their interest in the concerns of the African American community.
Chuck D had put out a tape to promote WBAU (the radio station he was working at the time) and to fend off a local rapper who wanted to battle him. He called the tape Public Enemy #1 because he felt like he was being persecuted by people in the local scene. This was the first reference to the notion of a "Public Enemy" in any of Chuck D's songs. The single was created by Chuck D with a contribution by Flavor Flav though this was before the group Public Enemy was assembled.
