For the first time since her appointment as music director designate of the Baltimore Symphony and the subsequent controversy that erupted when the BSO’s musicians complained that they had been shut out of the appointment process, Marin Alsop has taken the stage to conduct what will become her orchestra in 2007. Since those difficult days, Alsop and the musicians have been taking pains to demonstrate that there are no hard feelings, and “last night, the orchestra continued signaling its intention to work with Alsop, this time in the best possible way – giving her a strong, attentive performance of a program that very much reflected the kind of tastes she is going to bring to the organization.”
