These examples don't seem to fit the description of "artist performs the song while ignoring what's going on around them". As described, they just sound like videos that not much happens in, or that the artist barely appears in. Pasting then here in case I've misunderstood the trope, or if the videos do fit and just need a better description.
Soundgarden took this up to eleven with their video for "Spoonman". They're only in the video in a series of photos. The rest of the video is of the titular Artis the Spoonman. Chris Cornell later admitted they did it on purpose:
You see various pictures of us, but it's not quite the same as having us in your living room all the time. We're trying to maintain some degree of mystique about Soundgarden, I guess. I remember back when I was a kid, long before MTV, and the only way to see my favorite bands was to go to their concerts. It was an incredible experience. MTV has helped a lot of bands, but they've also helped rob a lot of groups of that special mystique. It's tough when you can see a great rock band on TV one second, then hit the clicker and be watching a soap opera or a sit com the next. That's what rock and roll has become for some people.
