The music was good, yada, yada, yada, so let’s get to the other things going through my head.
Millennium Park doesn’t allow dogs, except for service animals (which don’t include emotional support animals), so barking during the concerts there Is one of the few interruptive sounds you don’t hear. Keep in mind that I’ve heard all manner of disruptive noise during the music, but haven’t yet, though it’s probably only a matter of time, heard any of the people in the audience bark (as they have been doing in the Dawg Pound bleachers at Cleveland Browns games since 1985).
Even if they were permitted to come, the dogs might not be interested. Studies show that classical music reduces stress in dogs, but that, after a time, they become bored (as do many humans), and that in the long term they respond better to reggae and soft rock. It’s not clear what the time limit is on a dog’s attention span, but all but one of the numerous dogs at the one-hour Lake Shore Park concert held it together throughout and that one’s owner was kind enough to take it for a stroll as soon as the problem arose.
Now if we could only get concert ushers to take unruly human attendees for a walk.
