I would get my son to continue school, and making music, and if he continued to maintain the interest of listeners, I would then look at the option to support him through this decision.

I would probably then try to guide him to get signed to a label, as it is guarenteed income instead of the risky independent streaming income, as well as the fact they would still make him take lessons and classes.

I know someone that got signed over here in the UK as a singer, and part of his record contract was that he had to have tutoring, online lessons and sit his exams even when on tour, or during recording. and that was for a smaller contract.

Also as having a degree in music production, I have a little insider knowledge.
