Kenneth Noland, 1924-2010: A Tribute (Guggenheim, 1071 Fifth Ave., up through June 20). Four carefully chosen canvases painted between 1959 and 1981 by one of the masters of the now-unfashionable Color Field style of abstract expressionism. Needless to say, Noland is sorely in need of a full-scale retrospective, but this anti-blockbuster show contains the root of the matter (TT).
