Concerning Sierra Boggess, there are justifiable arguments for either direction taken. Being a concert, versus an actual production, I would hate to think that all our great singers would be precluded from being heard. In concert, its about the voices; and I would have zero issues with whomever the voices were that caressed the Bernstein/Sondheim score. If the singers were 40 and up; rather than the actual ages of Tony and Maria; I would be fine with it all. If the singers were Asian, French, German or Swedish this would not affect me either. It's about the soloist or singers and the spotlight placed upon their forte or specific talents. Now, on the other side of this, I would also buy tickets to hear the soaring voice(s) and glory of any Latino, as well. Sierra Boggess understandably wanted - and perhaps dreamed - of being able to bring her vocal interpretations to this magnanimous score. The decision(s) of Ms. Boggess were quite brave and honorable; but in terms of a concert, I sincerely hope that all furture voices from any age or group would ultimately get to be heard.
