Scholars may argue the aesthetics of blackness, but when black youths see jewelry and other shiny things in the media, they may not be aware of the effect on African-American communities and the American dream. Case in point: artist Satch Hoyt's 2003 work, "From Mau Mau to Bling Bling," an Afro pick featuring a diamond-studded black power fist. Art history professor Krista Thompson discusses Hoyt's artwork as well as the work of other leading artists in the post-soul era and the effects on black contemporary politics and society in OF SHINE, BLING, AND BIXELS. Free; ticket required. 2 p.m. High Museum of Art, Hill Auditorium, 1280 Peachtree St. 404-733-4444. www.high.org.
