Hip-Hop mogul Russell Simmons has joined the long list of celebrities contributing to the Live 8 Show held this Saturday in Philadelphia.

Simmons has signed on as a producer to the concert, which is being held to pressure the world’s richest countries-the G8--to cancel Africa's massive debts and double the aid for the continent.

“This is no charity this is about justice,” Simmons told AllHipHop.com. “This is to repair the past and to pay for the resources that are still being taken from Africa.”

Accepting to participate in the event was not a hard decision for Simmons, who dedicates a healthy portion of his time fighting on behalf of numerous civil causes.

Philadelphia is one of 10 countries holding concerts on July 2. Participating cities include London, Moscow, Paris, Berlin, Rome, Tokyo, Barrie, Canada and Johannesburg.

The Philadelphia show will be hosted by Will Smith with performances from Jay-Z, Alicia Keys, Sean “P. Diddy” Combs, Stevie Wonder, Black Eyed Peas and many more.

“All the Pop stars in the world can't do for Africans what Hip-Hop can do,” Simmons stated. “We must pull more resources. Some stars aren’t involved [and] they need to join in now. We need their help and we must press now to send a message to these world leaders.”

Celebrity presenters include Chris Tucker, Jennifer Conolly, Natalie Portman, Salma Hayek and others.

Organizers said the concerts could be the largest global telecast, as they hope to attract at least 4 billion viewers.
