Musician's attention

I think this sort of behaviour by musicians only happens at tourist places.

I am not sure of that fact and your experience may be different.

This was a very pleasant tourist restaurant in Cuba a couple of years
ago. I didn't have, or didn't want to use my flash, and the camera
calculated the shutter speed at 1.6 seconds. That's rather too long
for my handholding. Nonetheless, I liked the weird trails of light in
the picture and I decided to weird it up a little more.
