In the final installment of Abrons's series of avant-garde Eastern European artists who like to take their clothes off, RadioBallett - the Hungarian duo Bea Egyed and Milan Ujvari - makes its American debut with "The Nature of Love." This semi-autobiographical work has the two flinging themselves at each other, caressing tenderly and facing the audience fully exposed amongst strewn red flowers to represent the "demented state called love."
