4. Public Enemy, It Takes A Nation of Millions to Hold Us Back (1988)

Art Direction: Eric Haze
Photographer: Glen E. Friedman
Label: Def Jam/Columbia

Loosely modeled after James Brown's Revolution Of The Mind cover, photographer Glen E. Freidman placed a mean-mugging Flav and Chuck behind bars for their second album. It was a strong complement to the death row anthem "Black Steel In The Hour Of Chaos," but also served as an even more fitting metaphor for the group's politics: Even in the face of imprisonment, they would not be silenced.
