Like Fran, I have worked with several female vocalists over the years, both in band situations and as a duo. He makes some good points.

Fortunately, I've never had any issues as the relationships were based on mutual respect, and the desire to make the other, or others, sound good.

It has to be teamwork, and professional stage presentation and interaction is extremely important as many people "hear with their eyes"...not to mention the music should be well prepared and suitable for a female vocalist.

It also depends on the quality of the venues you play. Choose wisely.
