The Heinz History Center gets a bit edgier than usual with tomorrow’s public discussion called “Cultural Bodies: Sex, Violence, and the Body in the 1960s.”

The discussion is led by Brian Horrigan, the Minnesota-based curator who helped develop 1968: The Year That Rocked America, a touring show now at the History Center.

Horrigan “will explore the major shift in understanding and representation of the human body in art, culture, science and medicine throughout the 1960s,” according to the press release.

Ladies and gentleman, I give you “The Twist” and Axis: Bold As Love.

Horrigan will use still images and video footage in his talk. Much of the discussion will revolve around the portrayal of the human body — soldiers, Vietnamese civilians — during the Vietnam War. And then there’s nudity in film and theater, and in public; sex and the pill; and medical advances. Like many movies from that era, the talk is “suitable for mature audiences.”

Admission is $10 (and free for museum members), and includes admission to the exhibit.

The talk runs 6-7:30 p.m. 1968: The Year That Rocked America continues through May 12.
