Here is a live performance.
Music videos are elaborately edited, altered, digitally mutilated.
Live performance is more difficult to "edit" in real time.
But they're getting better at it.
If someone wants to evaluate the likely sex / gender of a performer, the live performance would be more accurate. But why trust either?
Whatever visual effects we see in a music video have been viewed dozens of times, for alteration. By design. That's where the agenda is.
NOT in the performers themselves or their peculiar personal histories.
