The two-day Made In America Festival got off to a rocking start at the Philadelphia Museum of Art as Jay Z entered the stage bouncing up and down, mimicking artist Rocky Balboa, with whom he shares a rag to riches story.

Jay-Z's "Made In America," played in the background as he took control on stage in front of nearly 50,000 strong crowd, Associated Press (AP) reported.

Post Jay-Z's entry from the rear, a pre-recorded video message featuring President Barack Obama played to the gathering stating Jay-Z story is "what Made In America means." Whilst urging the crowd to vote, Obama also noted that he listens to the rapper's hits on iPod, AP added.

Jay-Z performed hits including, "99 Problems," "Dirt Off Your Shoulder," and "Empire State of Mind," among others. Fellow rappers Pusta T, Big Sean and Kayne West also put up an electrifying show with hits such as "Mercy," "Dance," and "Can't Tell Me Nothing."

The event, noted as the first of its kind for Jay-Z comes packed with 30+ performances on three stages across two days. Saturday witnessed colorful and energetic performances including those from Skrillex, D'Angelo, and Passion Pit among several other acts.

Proceeds from the event are reported to benefit United Way chapters. Besides, the festival is also being shot as a documentary that is likely to be directed by Ron Howard, AP noted.

Soon after Jay-Z signed off the night with his hit, "...In Paris," fireworks decorated the Philadelphia skyline.

The event is also widely promoted on Social Media, with the facebook account attracting 28,321 likes with 13,059 talking about it at the time of writing this article.
