Host Evan Kindley talks with Simon Reynolds about his new book "Shock and Awe: Glam Rock and Its Legacy, from the Seventies to the Twenty-first Century." David Bowie may be Glam's greatest superstar, but figures as diverse as Roxy Music, Alice Cooper, and LA's own Sparks are also central to this most colorful and still-influential 1970's pop movement. The LA Times Jill Leovy drops by to recommend anthropologist Hortense Powdermaker's After Freedom, a study of 1920'as Mississippi; and which remains a stunning reminder of the severe oppression suffered by Black Americans under Jim Crow. This week's poetry reading is of Denise Levertov's Psalm Concerning the Castle.
