Musical digital artwork thing

Date: 8/31/2019

Some old friends bought a property near my house and they were having a little celebration in some kind of art studio. We were forming a big circle of people to share a giant group high five, but they were waiting for some more folks to show up so I sat down on an old church pew and looked up to see this huge piece of digital artwork. It was a guy and girl who seemed to be dancing in slow motion and I exclaimed that I had never noticed it before. There were swaths of sunlight shining on them and it was perfectly in line with the lighting of the studio. Then music began to play from the piece and I held up my phone to identify the song. It was by this brother/sister duo and I can't remember the name.
