Maryland has both.
Maryland's music program does not include the kind of coursework OP's DC would be looking for.
She will want to look for schools that offer a minor in music business or music industry that is open to non-music majors. Almost any school will offer a general music minor. Some schools, like Jacobs, may not have open admissions for certain programs, so she should check requirements to see if any audition or portfolio is required.
University of Miami, NYU, Syracuse and USC are known for their music business majors, but I'm not sure of their offerings for minors. JMU has a music industry major and minor in the event that you don't have unlimited funds or a kid with high stats.
