“As its 10th season runs from Aug. 11-27, the New York Intl. Fringe Festival is straddling the line between a grassroots cheerleader for offbeat legit and a seductive draw for commercial hopes. While few in the theater community imagine that all of this year’s 217 shows are suited for the big time, even fewer forget 1999. That’s the year ‘Urinetown’ dominated the fest, beginning its march to three Tonys and a two-year Broadway run. That and other transfers — including ‘Matt and Ben’ and tuner ‘Debbie Does Dallas’ — helped push the festival to a new level of relevance.”
