Jenny McAllister’s 13th Floor and Colin Epstein’s Twisted Oak get physical when the two dance companies each perform a 40-minute work at ODC Theater this weekend. The entry for 13th Floor is “Lightning Strikes Anonymous,” which is about people obsessed with electricity. Twisted Oak takes on “Fortune’s Fool: A Monster’s Odyssey,” an allegory that in addition to dance will utilize acrobatics, aerial work and clowning. The play is about five very different characters, all of whom have a different relationship with their addiction to being struck by lightning.
