I think Drew made an excellent comparison of the two full-length Swan Lakes, and I agree with every point she made. I would suggest, if you MUST see a Swan Lake, to see ABT's first, since it is, generally speaking, more traditional. Unless you are able to catch Mearns in the lead at NYCB's. Very special, indeed, but don't think the production is a typical staging of Swan Lake.
As for the one-act Balanchine version, I never thought it was supposed to be a literal Swan Lake, but an evocation of Balanchine's sense of the lakeside scenes, deliberately abstract. Martins seems to have wanted to apply that approach to the full ballet (as well as to his very misguided Romeo + Juliet), and it just can't, by definition, work.
the only parts of the '95 standard SWAN LAKE in the ballroom sc. said to be Ivanov's work are the Hungarian and Venetian dances, which in Martins's staging are his own choreography.
??? I thought Ivanov choreographed only the White acts, Petipa the "festive" ones.
