For more than six decades, Taylor has enriched the modern dance repertory with works that have challenged dancers, transformed music and invested the art with tonal nuances that defy the notion of abstraction. With Taylor, mood counts; and it certainly did at the Yerba Buena Center for the Arts Theater Wednesday, April 26, where the troupe opened its five-day run, under the auspices of San Francisco Performances. Taylor has been accused of crafting his dances with a smallish vocabulary of movement, but when you’re watching one of the great ones, like “Airs,” which opened the program, those considerations don’t matter. “Airs” (1978) is one of Taylor’s many baroque music dances; it is not the most iconic of them (that honor goes to “Esplanade” on tap this weekend), but is surely the most lyrical. The 10 musical extracts (all Handel and all recorded) frame a excursion for three men and four women. The moves are familiar — scooping arms, angled torsos, lofty leaps, descents on one knee, fast, lateral entrances — but they seem sculpted and posed with care for 18th century symmetries. [...] nothing, with the exception of Michael Novak’s breezy dancing, did much to save “The Open Door,” a new piece that received its West Coast premiere Wednesday. Novak is a host at a house party; he arranges chairs, welcomes guests, dances a bit and rearranges chairs It includes fat ladies falling and guys making eyes at each other, all set to a cruelly abridged version of Edward Elgar’s “EnigmaVariations.”
