Burn the Floor. It's been said that true moments of joy come mostly through two acts: sex and dancing. Burn the Floor combines both, as 16 hard-bodied, high-energy performers spin, thrust, and grind their way through one show-stopping number after another. This is not your grandma's ballroom dance, and choreographer and artistic director Jason Gilkison puts together routines that are always entertaining to watch. The weakest numbers come whenever things slow down and the dance relies on a true connection between two or more people, something that never materializes onstage. But Gilkison knows enough about his two-hour event to keep these moments sparse, and instead builds the evening around explosive group numbers, like a swing-club–inspired sequence or a tribute to Tina Turner. These pieces are the heart of the show, and you can't help but get caught up in the energy, talent, and sheer love of dancing radiating from the stage. Through March 19 at Post Street Theatre, 450 Post (at Powell), S.F. $49-$100; 771-6900 or www.burnthefloor.com. (Molly Rhodes) Reviewed Feb. 11.
Tennessee in the Summer. What's intriguing about this play "suggested" by the life of Tennessee Williams is that the playwright is portrayed simultaneously by a man (Daniel Albright) and a woman (Alex Alexander). They embody an angel-devil–like conflict within the Pulitzer-Prize–winning writer that results in his rampant alcohol and pill abuse, anxiety, self-loathing, and excessive whoring around. Plenty of stage time is devoted to Williams' long and rocky romantic relationship with Frank Merlo. In this imagined depiction, Williams is repeatedly adulterous and emotionally abusive, painting quite an unsympathetic central character. The brief moments featuring his mother, Edwina, and sister, Rose — who received a lobotomy in a sanitarium — serve to underscore his persistent fear of going insane. Merlo even refers to him as a "19th-century hypochondriac." What's tedious about Joe Besecker's script is that there is no character arc; Williams' character is a mess at the beginning and a mess at the end. The result is an imagined and clichéd portrait of a writer crippled by sex, doubt, and drugs. In the end, the female side of Williams warns the male side, "Don't fall into the myth of the tortured artist." Unfortunately, this play wants to perpetuate just that. Through March 1 at New Conservatory Theatre Center, 25 Van Ness (at Fell), S.F. $22-$40; 861-8972 or www.nctcsf.org. (Nathaniel Eaton) Reviewed Feb. 11.
