Is it permitted for a girl to attend a girls only concert that has a male singer? Girls generally sing a long at such concerts. Is it permitted to sing? Thank you
The male singer is not allowed to her the girls singing. Even though he can’t make out the individual voice of anyone, according to most poskim it is not permitted for the girls to sing.
