From City Paper music critic Lindsay Koob:
Apparently, the exhaustive rehearsal and performance schedule for R&J conflicted with planned rehearsals for the Mozart gig, and something had to give. Fortunately, Ellie Dehn — who is singing Donna Elvira in Don Giovanni — leapt into the breach. And we have every reason to expect a great performance from her in the mass. She has the kind of agile and creamy soprano that's ideal for the part, and she has apparently sung it quite recently. Rehearsal time for DG hasn't been as much of an issue — they already did it six times last year.
Sure, we regret that we won't get a second chance to hear Cabell. But if you hear Dehn in this glittering role, you probably won't be disappointed.
