guitarists for BOWIE, NIN and MADONNA

["Rick Walker" <looppool@cruzio.com>]

Can anyone confirm whether the guitarists for 
DAVID BOWIE,  NINE INCH NAILS and MADONNA 
are using live looping technology onstage?

I have heard that they do, but don't know for sure.


live loopers in other really big pop bands, per chance?
I know RADIOHEAD and BJORK's musicians have 
used the technology in concert.

thanks,   Rick
