“Grandiloquent” arrives at NJPAC as a live comedy event anchored by Gary Gulman, a performer known for treating language and everyday rituals as material rather than filler. The show sits in a New York–area tradition of stand-up that values precision, pacing, and close observation over broad punchlines. No specific NYC premiere history has been established for this program, but its preoccupation with speech and social habits reads as a local subject in a region where talk is currency. One clear strength is its attention to how words can inflate, evade, or reveal.
