PHILADELPHIA (TheBlaze/AP) -- Jay-Z brought out heavy hitters to support him at the "Budweiser Made In America" festival: Kanye West and President Barack Obama.
Obama appeared in a video, urging the crowd of nearly 50,000 to vote. West joined Jay-Z at the end of his set, performing hits like "Mercy" and "...In Paris" on Saturday night.
"[Jay-Z] got ahead because he worked hard, learned from his mistakes and just plain refused to quit," Obama said in the video.
The president added, "Whatever your politics or your party, you should vote this fall. Wherever you live, you've got a choice to make." Chants of "USA! USA!" broke out before the Obama video concluded.
Before taking the stage, Jay-Z made his way down the steps of the Philadelphia Museum of Art - made famous by Rocky - as his song "Made In America" played in the background.
Jay-Z headlined the first night of the two-day festival he curated, performing hits like "Empire State of Mind" and "Big Pimpin'" in a 90-minute show.
Skrillex, Miike Snow and Janelle Monae also performed. Pearl Jam, Run DMC and Drake will perform Sunday.
