High note: Grace (Katie Sigismund) pitched her cookies in the White House china room once, so she had to beg off the rest of the tour. As the newest member of a famed (and internally unstable) classical string quartet, she'll get another chance, but what follows isn't quite what she had in mind. The story plays out in Michael Hollinger's Opus, which director Kyle Donnelly has mounted nearly unerringly—great stuff. The show plays through April 26 in Copley Auditorium, 1450 El Prado in Balboa Park. $29-$59. 619-23-GLOBE, www.oldglobe.org.
