I was about to go on a mild tirade about King Crimson, while a bit busy, still being music that followed the norms well enough, when I realized I have never listened to the project you are referring to. In fact I looked up Brian Eno, because I recognize his name, but I can't tell you that I recognized any of what he's credited with on Wiki. I guess I have a rabbit hole to fall down today.

Not sure why would take something where I'm talking about a music scene and apply it to an individual band, but sure.

There are bands that only ever sell or perform in Ireland. That is the Irish music scene. Just like there are footballers that play in Ireland, and films made in Ireland. And there is the British music scene, which includes Irish people selling there, performing there. And a British football system, and a British film market. But you wouldn't call individuals or bands from Ireland performing there British, any more than you'd correctly call Roy Keane or Cillian Murphy British.
