If, like the NY Times dance critic Alastair Macaulay, you are “only slightly acquainted with the work of three of these artists (Beth Gill, Ralph Lemon, Sarah Michelson) and not at all with three others (John Jasperse, Jennifer Monson, Anna Liv Young),” or even if you are,  check out the Dance On Camera Festival kicking off today and running til February 2nd at locations throughout the city.  But mostly at Walter Reade Theatre at Lincoln Center. Lots of cool stuff and a good chance to learn about choreographers you may not have been exposed to live.
