Parent wants to keep kid out of band due to academic issues?

I had a parent for a beginning band student reach out to me, the student services director, and one of our sped teachers, asking why their child was signed up for band, as they had previously talked to the student services director about academic concerns (valid concerns, not just some F's) and concerns with their students taking band. They say they talked to the previous elementary music teacher (who didn't have a degree and hasn't been teaching music for two years) and decided that band would be overwhelming and learning to read music would be too frustrating. They don't want their kid to participate in band (or any specials) until the kids is past their academic issues.

How would you approach this? Thinking about the parents concern, I feel like there's a lot of research that could point out that music is often beneficial to student learning, but I also can't just go into this citing research papers. Are there articles you like to share to show the benefits of music in a students education? I'm not trying to change the parents mind per se, but I don't believe they have accurate information.

Obviously, I am going to have to talk to the staff that didn't include me in this or even reach out to me with questions. This is the second time they have made decisions about student in my class without including me (the last was a sped kid that loved band and just needed a little support that they just fully removed without talking to me).
