What do a groceries-carrying bear and a jazz-playing blow-up doll have in common? Well, nothing really, but that’s the point of musician Seth Paynter’s “Sex and the Absurd,” a performance art piece that’s part of DiverseWorks’s Sunday Sonorities. “Sex” consists of avant-garde improvisational jazz and short skits featuring “light acting and even less dancing.”

“These five pieces will lend themselves equally to the erotic and the absurd and hopefully make people scratch their heads,” says Paynter. In keeping with the absurdist theme, he promises that audience members will meet “women with tennis rackets, Satan and maybe a robot.” “They’re aspects of my personality I’d like to explore,” he says. Hmm…good luck with that, Seth.

Pianist Danial Kovaly opens “Sonorities” with a performance of Shakespearean poetry that he has turned into a libretto, which will be accompanied by a percussion ensemble.
