MC, or Master of Ceremonies, is a performer who engages the audience and often leads the event, particularly in music and hip hop culture. In this context, an MC typically raps, delivers lyrics, and interacts with the crowd, showcasing their lyrical skills and charisma. In hip hop, the role of the MC is crucial as they not only entertain but also convey messages through their verses. Famous MCs like Eminem and Jay-Z have shaped the genre, using their platform to address social issues and personal experiences, making the art form both impactful and relatable.
