The fourth annual Pathway To Paris concert will be held at the Masonic in San Francisco on September 14. Organizers of the event, which caps the Global Climate Action Summit, confirmed the lineup. All proceeds from the evening will be donated to 350.org, Pathway to Paris, and the United Nations Development Programme.

Grateful Dead/Dead & Company guitarist Bob Weir and legendary singer-songwriter Patti Smith will headline Pathway To Paris ’18. Red Hot Chili Peppers bassist Flea, Rock & Roll Hall Of Famer Eric Burdon, Tenzin Choegyal, French performer Imany and Pathway to Paris Founders Jesse Paris Smith and Rebecca Foon are also among those aboard.

Renowned artist Olafur Eliasson has prepped choreography that will engage audience members to create an interactive collective artwork. The crowd will be asked to hold up a Little Sun solar lantern with the aim of showcasing a visually striking solar-powered “sunrise” which raises awareness for climate action and energy equality.

Pathway To Paris aims to celebrate climate action. The concert “will focus on the potential for cities to push for, achieve, and go beyond the climate targets highlighted in the Paris Agreement” as per a press release. “In the world of music, the best way to improve is through collaboration. This is the same with the critical issue of climate change,” Jesse Paris Smith said. “We must join together to make this the most ambitious collaboration of our century. We will not be able to implement crucial and challenging solutions to climate change, plastic pollution, and all urgent environmental problems as long as we stand divided. Inseparable from the issue of climate change is the need for world peace, global communication, and an international collaboration unmatched by any event in human history.”
