If you know anything about the music industry, I need your help ASAP.
One of my voice students (age 11) is involved in some talent search and has had a callback. She has to make a demo CD of at least four songs. She and her mom are in the process of choosing songs, so I gave her my cellphone number to call me if she had any questions about a piece they were considering. I just got a voicemail from her mom about playing on her daughter's demo, which they're recording on Thursday after her lesson with me. I'll go ahead and say that my other voice student is in a similar situation as this one and his mom has asked me the same question as well. I'll only be playing one song with them, the rest will be from backing tracks.
My problem is not in doing it, but you know as well as I do that I'm not doing it for free. Studio rates are $50/hr. What should I do now? I've never been in this situation before.
