Shalom, Can a female Jewish professional singer, who performs exclusively to women, have a Jewish male producer, who is hearing her songs? Thank you

Shalom, Thank you for your question. In general a woman is not allowed to sing with men listening. However, there is room to allow a professional producer to listen to a woman singing in the course of his work in producing her songs. This is based on the law of being occupied with one's job. In such a situation the halacha understands that the person will be so focused on their work that they will not be swayed to licentious thoughts. This is the same rule that allows a male doctor to examine a female patient. Blessings.
