Well, there's plenty of food for thought here. Generally we don't have this kind of worry - a group of modern dancers, or the cast from the touring company of "Footloose" or "Mahalia" just don't go out on the town gigging !And yes, there is some question if the "so-so" critic was all that informed. I agree we shouldn't be booking "so-so" acts, and in this area of presenting (jazz), one person's meat is really another's poison. In general, jazz has not been a big seller on our stage for years - which is why we strive to accomodate groups touring through; we're promoting artistic diversity and that sort of thing.
We will know next time -- if it's a small jazz, folk, or bluegrass act -- to watch out for this particular little wrinkle!
