For the second work of its 2017 fall season, BalletX returned to the newly spruced up Wilma Theater with a reprise of a 2013 commission to internationally in demand choreographer, Nicolo Fonte’s “Beautiful Decay.” Two sets of well-known Philadelphia-based guest dancers alternate during the run. On seeing it the first time with Manfred Fischbeck and Brigitta Herrmann, years ago, and this time with Hellmut Fricke-Gottschild and Brenda Dixon Gottschild in the alternate cast, I find the title even more wincingly uncomfortable.
