Philadelphia - 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.

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 on Sunday. - Sapa-AP
