Eighty-six promising young opera singers gather in Israel for an opera boot camp. “Survival in the dicey world of opera — which can demand more years of preparation than brain surgery, without the guaranteed payoff — was a subtext during the 17th summer of the Israel Vocal Arts Institute’s program. Participants have a four-week schedule of one-on-one voice, diction and role coaching, and almost nightly performances, with public master classes, concerts and eight fully staged productions.”
