Bono helps make this point in this interview:
If you take musicians away from the stage too much, they become quite abstract in their heads. They start to use words like “interesting.” But people don’t want to see you do something interesting. They want something passionate or wild.
“Interesting” is the moment musicians scratch their chin. It ruins great and dramatic music. You listen to the Sex Pistols or Nirvana or the first MGMT album and you don't scratch your chin. You say, “Wow, that’s extraordinary.”
And I know that scientists are always saying something is interesting. I’m guilty of it myself, and I know because one of my research students told me flat out, “‘Interesting’ is overrated!”
