Through September 16 - Sublime Seas: John Akomfrah and J.M.W. Turner at SFMOMA. John Akomfrah's Vertigo Sea is an absorbing and wrenching piece of film-making, and I wept multiple times when I saw it at SFMOMA last week. Capturing the ocean in all of its magnificence at the same time that he chronicles the brutality humans have practiced in it, Akomfrah deftly weaves together multiple strands: the whaling industry, the slave trade, nuclear tests, animal cruelty thinly disguised as "exploration," the current refugee crisis, migration, climate change. And he sets it all to a soundtrack that incorporates sparse music, natural sound, news reports, and lines from the likes of Herman Melville and Virginia Woolf. The painting that you see when you enter the screening room and again when you exit is a tour de force by J.M.W. Turner on loan from the Tate, depicting turmoil and tragedy (as only Turner can), and its pathos resonates even more strongly after viewing Akomfrah's work. This morning I woke to the heartbreaking news that with only 12 vaquita porpoises remaining in the wild the species will almost certainly go extinct soon, and I sat on the floor and wept again.
