Around these parts, permaculture normally means mandala gardens, bare feet, western Sonoma County and tree kale. But it’s more than an alternative farming method; as a portmanteau of “permanent culture,” it’s a way of observing social and agricultural systems holistically, and of studying the relationships between the parts of a whole. The AfriCali eXperience shines light on the oft-neglected social side of permaculture, with music by South African–bred artist Eyezon and the People Like Us Band, Inner Riddim, King Hopeton and more. Art and sustainable social systems come together on Thursday, June 7, at Aubergine. 755 Petaluma Ave., Sebastopol. 8pm. 707.861.9190.
