[Dixielandjazz] Columbia's echo

[TBW504 at aol.com]

I doubt the stairwell story. I was once a BBC recording engineer and we had 
an echo chamber consisting of a bare-walled underground chamber with a speaker 
at one end and a microphone at the other. It worked splendidly except that 
extraneous noise - the rumble of passing traffic some distance away; even the 
occasional tube train - often made it unuseable. A stairwell would, I suggest, be 
virtually useless, although I have no doubt the half-wits at Columbia added 
echo.
