Margarita Pracatan is at least 60, extremely Cuban and quasi-known for her wacky covers of pop songs. They are irreverent not just to their source material, but to the ideas of melody and rhythm. On Friday, she performed her one-woman show, Stranger in the Night, at New York's Laurie Beechman Theater under the direction of Zach Udko. It was one of the wildest entertainment concepts I've ever witnessed. For over an hour, Pracatan stood in front of a pidgin-English PowerPoint presentation and discussed her love of money, her hatred of marriage and her frequenting of hotel bathrooms with her riffs on pop songs like Lionel Richie's "Hello," Katy Perry's "Teenage Dream," Carly Rae Jepsen's "Call Me Maybe" and Maroon 5/Christina Aguilera's "Moves Like Jagger" interspersed. Before singing "Jagger," she told the crowd, "You can sing with me, 'cause I don't know this song." Every time she stepped up to the keyboard, she regarded it warily, as if it were her first time ever setting eyes on it. I believe that her "Teenage Dream" rendition linked to above uses the wrong preset beat. Oh well, incoherence is her aesthetic.
