My son’s summer at Interlochen was transformative. Mine was considering music performance and his experience that summer solidified his decision. He just graduated from conservatory and is a happy, working musician.
Does your son know what program(s) he would attend there? It sounds like he has an array of interests so is he looking at jazz, composition, orchestra?
You would need to ask camp admissions, as I am not sure how much participants are able to pursue activities/mentors outside of the primary area in which they enroll. So if for example, your son was enrolled in jazz and wanted to explore music production and composition, is the curriculum flexible enough to allow it?
The faculty was amazing. Be sure and apply for financial assistance.
Feel free to message me if you have other questions.
