Female backing/lead singer for recording/touring band

We are a name, signed, recording and performing/touring band who are successful, credible and critically acclaimed.
We are just finishing a new album and starting pre-touring rehearsals. We are headlining a festival in Europe in late August so time is short! Our new album is scheduled for release in September.
We'd like to find an intelligent, creative, enthusiastic, fun-and-music-loving new member. It would be a bonus if you can also play some guitar. Age unimportant.
Our music is melodic, lyrical, harmonic and very dynamic.
