The 15th annual New York Intl. Fringe Festival has lined up a slate of some 200 productions, including the latest tuner from Greg Kotis and Mark Hollman, authors of early Fringe hit “Urinetown.”Also on the docket are a return from Pittsburgh troupe PigPen with “PigPen Presents: The Mountain Song,” autobio spoof “I Light Up My Life: The Mark Sam Celebrity Autobiography” and the requisite list of tuners with wacky names, including “Jersey Shoresical: A Frickin’ Rock Opera” and “The Musical That Killed Everybody!” It was “Urinetown,” a Fringe preem in 1999, that effectively cemented the Fringe trend of cheekily-titled musicals aiming for future life. “Urinetown” went on to a stint Off Broadway and eventually to Broadway, where it opened in 2001 and ran for more than two years. A more recent Fringe hit, “Silence of the Lambs” parody “Silence! The Musical,” is set for an Off Broadway commercial run later this summer. Kotis and Hollman’s latest comedy, “Yeast Nation (The Triumph of Life),” centers on primordial earth’s first life forms. Show, previously seen in Chi and Alaska, makes its New York bow at the Fringe. The 2011 Fringe runs Aug. 12-28 in 20 Gotham venues.
