Now in the event's third summer, Mad Decent and Diplo have teamed with Diesel and Jelly to expand the party across the country.

The Mad Decent Block Party tour kicks off in Philadelphia on Saturday (July 31), before traveling to New York, Los Angeles, and Chicago over four consecutive Saturdays from July 31st to August 21st.

The event promises music, carnival games, yummy food, super secret guests and all for FREE!
