Bear in mind that the Boston Symphony will release its own commemorative boxed set of historic broadcast performances this Spring. This package was originally promised last Fall, to coincide with the Symphony Hall anniversary, but, when I tried to order it for Christmas, I was told it was being held up for several months over several technical and legal (estate/licensing?) issues. The promotions mention many spectacular performances led by renowned guest conductors, but no names are mentioned beyond Ozawa, Munch & Monteux; I wouldn't be surprised if a Tennstedt, Bernstein, or Barbirolli excerpt turned up as well. You might want to wait to see what shows up in the final box of 10 CDs. Dick Claeys
