One of our most versatile choreographers, Mathew Janczewski creates pieces that range from meticulous to rambunctious. Whatever the theme, Janczewski’s dances and his splendid company explode through space in cascades of full-bodied movement. Twenty years ago, he created ARENA Dances. For this anniversary, he’s taking the considerable risk of presenting a one-night-only program of works old and new at the Fitzgerald Theater, a venue not particularly known for dance. His newest work, “Anthem,” set to music by composer Michael Nyman, is inspired by Janczewski’s youthful memories of moving through space, which he continues to do with the ease and noblesse oblige of a celestial gymnast. It will be terrific to see him reunited with his longtime muse, Amy Behm-Thomson, in the premiere of “Duet at Home.” Other works include his 2010 “Not so good at standing still” and “Matador,” a dynamic foray into the psyche, emotion, and elegant ruthlessness of a bullfighter.
