It's their Earth Day party
and they'll be green if they want to

The eco-friendly souls at Artists for Humanity will throw a giant party Saturday -- Earth Day -- at their environmentally correct EpiCenter warehouse.

''We'll deliver all of the fun, with none of the toxic emissions," says founder Susan Rodgerson. ''We want to bring hip and aware Bostonians together to recognize the EpiCenter's leading role in environmental sustainability." She pledges that the event is strictly a party -- no speeches, no pitches, ''just entertainment" from 8 p.m. to 1 a.m.

The EpiCenter combines gallery space, art studios, and offices, using solar roof panels to generate electricity. It was designed in part by architect Carlo Lewis, now 28, who helped found Artists for Humanity with fellow teenage artists and Rodgerson when he was just 13. After school and on weekends, the EpiCenter buzzes with young artists paid hourly to work in painting, drawing, and graphic design, among other arts.

''We plan to do this every Earth Day," Rodgerson says. ''We're making a statement that green is good and that revival of the planet is where it's at."

The EpiCenter is at A and West Second Street. Tickets are $70. For information, visit www.afhboston.com. KATHLEEN McKENNA
