I often hear "musicians" say they go cold if they have to stoip for long so they tend to be at the "ensemble" end of the spectrum. There are a lot of singers who don't play or only to accompany themselves so they are the "solo" group (??). As a lister of venues I think in terms of the two ends of that continuum and see a less populous middle ground - even for people who frequent either who but tend to want their night in one of the 2 end "boxes".
As long as the people come in sufficient numbers and it is enjoyed by them the only problem is what you call or describe the "do" as - because that will attract people of that preferrence.
