Interesting thread guys.
While we label one another and try to to decide what kind of person adds musical value and who does not, the public we want to play for has made absolutely NO differentiation between musicians, singers, DJs, Karaoke etc. To them, it's all just "live music"
So the question that remains for each of us is: if you want to make money playing for those who make no differentiation, which niche works best for you? Because in the end, they all get about the same respect and the same paycheck
Pick one and go for it.
Or, take the high road and decide not to. But the trend is in the direction of singles acts of one kind or another; whether or not you are part of the trend is your personal decision.
