If you stumble upon the original DG CD issue (415367-2), it will be slightly edited. About four minutes of repeated and previously herad bars will be absent. Back in the 1980's when first issued on CD, the technologhy was just not there to present the performance entirely complete on 2 CD's, as heard on its original 3 LP issue (DG 2709 099). This re-issue (DG 453055-2) has restored all the missing bars. This remains the most exciting complete "Swan Lake" out there. The only complete "Swan Lakes" which are more exciting than this, are the live Ozawa/Boston performances, dating just a week or two before this recording was made by DG; and those live performances are locked in The Boston Symphony Orchestra archives!!
Update: I just noticed (quite some time later) that the pamphlet which comes with this re-issued 453055-2 edition did not get an exactly perfect revision. The restored bars are all on CD # 2, tracks 7, 19, and 20 respectively. The longer playing timings have been updated, but DG missed a couple of details on the text portion. Each number of the score is described in detail, track by track. In the original 415367-2 CD booklet, it is notated in small print after tracks 7, 19, 20 on CD # 2, "abridged." In the 453055-2 booklet, it still says "abridged" in the same areas of the text, although they are now thoroughly complete and restored. Most likely someone didn't proof read thoroughly.
