When playing with a combo or big band in an echo environment like a gym 
or a shopping mall, my best break is when I know the book, the head 
arrangements, musicians' approaches to time, etc., because of 
longstanding playing with the group. Hard to explain, but based on this 
prior knowledge we can visualize what we can't hear directly, and 
everybody "humors" everyone else as we lay into the time and phrasing. 
There's a limit to this that Jim has described but I've never been in 
that bad a situation. Also, it's much worse if an electric guitar or 
piano are playing a flat four-on-the-beat rather than comping, because 
the delay in 4/4 is very unforgiving.
