BARCELONA, Spain (AP) — Barcelona’s opera house has reopened and performed its first concert since the coronavirus lockdown. To an audience that didn’t have to worry about social distancing. Instead of people, there were 2,292 plants, one for each seat in the theater. Monday’s concert was also livestreamed for humans to watch. The event was conceived by a Spanish artist who said he was inspired by nature during the pandemic. At the end of the eight-minute concert, the sound of leaves and branches blowing in the wind resonated throughout the opera house like applause. The theater says it will gift the plants to local health workers as a thank you for their efforts during the pandemic.
