LA Weekly has a longer looking into an opera that takes you into different limos from the same people who gave us a opera at Union Station with headphones.
"You buy a ticket online. You get an email telling you to report to a
certain intersection, in or near downtown. Four audience members show up
at a time. For the first chapter you'll probably get in a limo. Inside,
as it drives, singers perform, a musician plays. Or you might have a
non-limo experience — in a building, a park, a plaza. Or you might have
on your head a sensor reading biofeedback, so that your mood determines
the type of music you hear. (Rejected ideas includeed iPads and drones.)"
