yep, he did the same thing dring the performance I saw I think it was at the Felt Forum in Madison Square Garden I think the song was "Lay Your Hands On Me" ?
he turned his back to the people and fell backward (talk about "TRUST"!) He seemed to float on a sea of up-stretched hands as the people supported him effortlessly and passed him around while he went right on singing, until they set him gently back on the edge of the stage. AWESOME!
Our experiences with 'progressive' seem to have a whole lot of common ground.
The one tour that got little if any attention in the progressive world was the 1993 David Sylvian & Robert Fripp tour in support of the incredible album "The First Day".
Many of us have seen Crimson live, I saw tours that included Bruford, Levin, and Belew in the double-trio format. "Discipline", "Beat" … "Thrak". But this tour with David Sylvian was unbelievable in power and atmosphere. Fripp played straight out power fuzz and tape-looped ecstasy jam with guitarist Michael Brooks and Trey Gunn on stick … here's "Darshan", the funkiest guitar jam ever in the progressive scene.It' s long, but it is great), and I am so glad to find the tour was filmed:
Bringing back memories of Adrian Belew in Elephant Talk.
As far as replacement singers sounding too much like the originals... if they picked someone with a new sound then people would complain that it doesn't sound like the "old" stuff. Just can't win...lol.
