Okay kiddo, let me tell you about DJ Kool Herc. He's a man who is famous for being one of the early pioneers of a kind of music called hip-hop.
Hip-hop is all about using music to tell stories about real-life experiences, and it started in New York City way back in the 1970s.
Now, DJ Kool Herc was one of the first people to figure out a really cool way to make hip-hop music - he would take two records and play them at the same time, using a technique called "mixing." This allowed him to create new sounds and beats that people had never heard before!
He would also throw big parties in his neighborhood where people could come and dance to his music. These parties got really popular, and before long other people started copying the style of music that he was making.
So in a way, DJ Kool Herc is like the godfather of hip-hop music. He showed everyone how to make it, and helped it become the global phenomenon that it is today!
