Are the water wars inevitable? In hopes of staving off that bleak prospect, choreographer Marielle Amrhein of Dance Monks has joined the international movement to “daylight” urban creeks (i.e., to bring them above ground) and revive the natural sources of water beneath our feet. To that end, she’s hosting a guided walk and site-specific performance at Strawberry Creek this weekend. NOMAD: The Blue Road will begin at the western end of the UC Berkeley campus (Center and Oxford sts., Berkeley) and meander to Strawberry Creek Park, with pauses for dance and music along the way. A notable roster of Bay Area artists will share the journey, including dancers Dohee Lee, José Navarrete, and Debby Kajiyama, violinists Jennifer Curtis and Pauchi Sasaki, and environmental artist Lauren Elder, whose recent work has been dedicated to exploring water, ecology, and climate change.
