Not at all (as I said in prior replies). The whole point of me asking is because I am a guy, so obviously I have zero experience or knowledge of what it's like being a female going to a music audition with nothing but strange men alone. Since this came to my mind as a possible concern, I felt it prudent to reach out here and see if people could offer some insight or what their experience was. We had a female from our community say that it is a concern for her, a few guys asked their SO's who said they would be uneasy, and you have replied (which I appreciate) saying it's no big deal for you.
Quite honestly I hope it isn't a big deal for applicants to audition with us and I believe there is a good chance it won't be one, but to give you a question in return, what exactly is at stake by doing what I suggested? (public place, being open to a "chaperone", or anything else reasonable).
I was worried I might come off sounding a bit confrontational with that question, but I had to ask. My apologies. I think it's great that you ask the question to others in your community--online and in a physical reality. You don't know until you know. I would add that different women will have different perspectives. I started playing in bands when I was very young, so I am very used to being around a lot of male musicians.
To answer your question... First let me quote PCake (a couple other posters said something similar to her) "i would have felt weirded out if someone told me i could bring someone or told me anything for my "comfort." If renting a rehearsal space for an hour or 2 is not an option for you guys, it really isn't out of the ordinary for all of you to meet at a coffee shop with the singer to discuss band stuff. There you can make a decision about an audition date/time. You can let her know that you all rehearse at the drummer's place. If you guys perform in public, invite her to a show. There she can check the band out, meet with you and you all can discuss afterward about the band and your long term goals.
A band that I played with in the mid 90's, consisting of me & 2 guys who I am still super good friends with, had me see them live first. We met afterward in the club and talked for a while. We talked about what music we like, what our goals were, how much time they expected each one of us to invest in the band, how much rehearsal space cost, etc. There we decided on a time for an audition. That initial meeting was beneficial. I got a sense of who they were and they of me. We used to ride together to rehearsals 4 nights a week crammed in the singer's little Toyata pickup. lol! Different times.
I think meeting beforehand with a musician you hope to audition is crucial. I don't know why I haven't done that all the time. I've wasted time auditioning people who didn't have their chops together or just weren't on the same page as the rest of the band or who just didn't click with all of you. Maybe you already know this, if not, I can't tell you how awful it is to have to be around someone you realize you can't stand for several hours for a rehearsal, at a show for an entire evening/night or worse on the road for several weeks.
Anyway, I hope that helps. Don't worry too much about the safety thing. A woman will know what's safe for herself. Also, if she is of the timid type, maybe you don't want that type of a singer to front your band? Just a thought.
Good luck in your search! I think it's really difficult to find the right musicians. And good singers who have that voice you want aren't a dime a dozen.
