Well, I've played music (electrically amplified blues) in a "beer joint"
that was acoustically VERY live...only non-reflective items in it were
the listeners! At times, I couldn't hear much from the bassist...but I
could move a few feet and hear MAINLY the bassist! Made setting up the
PA a bit of a task...
