Way Up High. Loose Screws is a wonderful name for a tap-dance company, referring as it does to the screws on tap shoes that must be loose enough to let the taps jiggle and click. Would that it also applied to the sensibility of the company's artistic director, Jenn Rose, composer and associate director Dan Kazemi, and associate artistic director Megan Nicole O'Brien. Their show at First Unitarian Church of Philadelphia on Tuesday was sweet, girly, even new-agey in its attempt to portray the story of the dancer who represented the color black and deconstruct it into the colors of the rainbow. Hence, the title Way Up High, an allusion to "Over the Rainbow."
