Another lineup change is on the books for Tuesday, Oct. 6's Forbes Under 30 Music Festival. Following N.J. rapper Fetty Wap's motorcycle accident last weekend that left him with a broken leg, A$AP Rocky is set to serve as replacement.

Rocky returns to Festival Pier — where he just made a stop on his co-headlining tour with Tyler, the Creator — to round out the bill, which includes Hanson, Lindsay Stirling and Shawn Mendes with emcee Ronan Farrow.

It was previously announced that Fetty Wap and Shawn Mendes would replace original headliner Avicii, who's cancelled many of his remaining 2015 tour dates.

In any case, this seems to be the solidified lineup for the free concert. Tickets are now available for the first 4,000 participants who create an account with Global Citizen and send out a tweet promoting social activism. Seems simple. Just a tweet and you've scored yourself a pair of tickets.
