The high-water mark in the unsuccessful 2008 campaign to pass Proposition H, the Clean Energy Act – a partial public power measure that Pacific Gas & Electric buried with a deceptive, $10 million propaganda blitz – was arguably when the hit band Cake played a benefit concert for the measure at The Independent.

Tonight (July 1), the ever eco-conscious Cake returns to that venue with a similar mission, this time dubbed Climatepalooza 2010, with the goal of building a solar roof at the Telegraph Hill Community Center, honoring a request by Telegraph Hill political powerhouse and San Francisco Democratic Party chair Aaron Peskin and Prop. H campaign manager Julian Davis, who has a personal relationship with some band members.

“Climatepalooza 2010 promises to be a wonderful event. It give folks a chance to hear some great music and do the right thing for the environment, and it also supports Tel-Hi, a vitally important neighborhood institution,” Peskin said in a statement released by the nonprofit group One Atmosphere, which has also been involved in organizing the event.

That group, which has worked Al Gore, Nancy Pelosi, and other party bigwigs also got a quote from Mayor Gavin Newsom (who opposed Prop. H): “It's great to see San Francisco putting together events like Climatepalooza. It combines the best of San Francisco – caring for your neighbors, doing something positive for the environment, and having a great time. Everyone needs to help in the fight against global warming. This is a terrific way for people to get involved.”

Apparently Cake and the power of the sun can create unlikely bedfellows.
