I’m a little perplexed by this. The Los Angeles Philharmonic program booklet implied strongly that Dudamel was conducting the complete 1910 version of the ballet. Stravinsky made three suites of “The Firebird,” though, and changed the orchestration for the suites of 1919 and 1945.
Here’s where it gets confusing. Dudamel and the Phil definitely played the complete ballet this weekend, not a suite, but there was one aspect of the scoring that I believe — but don’t know for sure — was taken from one of the suites. That is in the middle (not the end) of the “Infernal Dance,” where there were fortissimo solo trombone glissandi, which are NOT in the 1910 version (I just listened, with score), but are in at least one of the suites. Did Dudamel plug in an “Infernal Dance” from one of the suites? And if so, is that OK? I’m not so sure. Can someone at the L.A. Philharmonic enlighten us?
