Along with some of music's hottest artists, the legendary rap group took part in the best music festival to hit the east in a long time.
Dressed in the classic adidas attire, Run and DMC rocked the mic all night with a 40-minute set. Rev Run shouted out the thousands of fans who looked on from the crowd, asking everyone "Do you feel good?" while the crowd replied, "Real good!"
Angela Simmons also dished about her daddy's performance on Twitter. The young businesswoman shared backstage photos of her father performing, as well as pictures of her adventures backstage at Made In America.
While backstage, Angela ran into Philly-born artist Santigold and kicked it with her little brother Russy Simmons.
The performance was definitely one that you would have hated to miss.
RIP Jam Master Jay.
