The Roots, Cypress Hill and Lyrics Born will join a superstar cast of artists participating in The Echo Project's annual eco-responsible music and arts festival, which is taking place in October on a privately owned 1250-acre farm just outside of Atlanta.

Stephen Marley, The Killers, Phil and Friends, moe., Michael Franti and Spearhead and the Dirty Delta Blues Band are among the artists who will perform during the three-day camping festival, which takes place along the Chattahoochee river front from October 12-14.

The Echo Project's goal is to use music and arts to educate the public about alternative energy sources, waste management, recycling initiatives and other ways to protect the environment.

The event utilizes the most recent trends and technologies in the industry to power the concert.

Additionally, thousands of supporters will also participate in a major Chattahoochee river clean up, prior to the festival.

Tickets to the three-day festival start at $120.00. For more information visit http://www.the-echoproject.com/.
