The most memerable moment of any Laurie Anderson show I've seen came
during this tour where she made rather stunning use of silence. Perhaps
she was looping it...
I have to admit, the memorable moment of the last tour was when she had pencils and paper distributed among the audience for those annoyed at the "no-photos" policy!
(The other memorable bit was waiting in the cold London night for her to emerge, to meet her; sadly, no sign after four hours...)
