This TU Dance concert is an embarrassment of riches. New York-based Ronald K. Brown, known for his fusion of African and modern dance and his “spiritual elasticity,” premieres “Through This Light,” a work that features traditional music by Conjunto Folklorico Nacional de Cuba and other world-music artists. TU’s artistic co-director Uri Sands reprises his 2016 “Matter,” a searing work responding to violence and racism. Kyle Abraham’s “Candle” and Gioconda Barbuto’s “FOOTPRINT” complete this dynamite program. The best reason to go is the inimitable TU dancers, whose extreme virtuosity and stylistic range are matched only by their emotional depth.
