Grammy award-winning band Maroon 5 will perform for more than 25,000 members of the green building community at the upcoming Greenbuild International Conference & Expo, Oct. 4-7 in Toronto, Canada.

"We're thrilled to host one of music's biggest bands, Maroon 5, for what will be an unforgettable evening of inspiration and celebration," said Kimberly Lewis, vp, conferences & events, USGBC.

"The band and I are looking forward to heading to Toronto for Greenbuild 2011," noted Maroon 5's Adam Levine. "The environment is a cause that the entire band deeply cares about and we are excited to help kick off the 10th anniversary of this important event."

The concert, taking place the evening of Oct. 5 at the Air Canada Center, will follow an inspiring keynote by Pulitzer-Prize winner Thomas Friedman, and a panel on USGBC's Resiliency Agenda, featuring medical anthropologist and physician Paul Farmer, and ABC News political commentator Cokie Roberts.

A long-time champion for the environment, Maroon 5 went carbon neutral for its 2007 tour, performed at the Live Earth Inaugural Ball in 2009 and was honored at the 2006 Environmental Media Awards. The band has also taken the stage in support of Haiti, USGBC's target area of aid and sustainable development through its Project Haiti campaign. The band helped launch the Haiti: Aid Still Required campaign movement earlier this year, and played at "A Night to Benefit Haiti" in Los Angeles.
