Mendieta's work is angry and confrontational - there's a lot of blood and a lot of nudity. Its appeal isn't compromised by her beauty. It's mostly video and photography of installations and scenarios she set up. A couple of works feature her nude and bloodied body simulating a rape and murder scene. Apparently she invited unwary punters along to apartments and outdoor locations where they'd happen upon her apparently lifeless and abused corpse. Now that's art that'll shake you up. The most disturbing piece for me was a video where a nude Mendieta is handed a just decapitated chicken and she holds it (gingerly) by the legs while the unfortunate fowl bleeds out after some increasingly feeble flapping of its wings, and the occasional slow fall of a poignant feather. Another piece shows her lying under a bloodied sheet with a large cow's heart on top. (Shades perhaps of Alice Maher - certainly they share more than the same initials.) This last image is a disquieting harbinger of her ultimate fate. There are other pieces suggestive of her interest in Cuban voodoo - Santeria, and a lot of images and sculptures of her body imprint in wood and earth. I exit the Hayward shaken and stirred and when I lunch at the BFI nearby I eschew the chicken option.
