So... if this place is supposed to be like a normal High School/University, it would stand to reason that there are musicians, and many different types of musicians, (i.e. genres). Now, I have assembled a list of a few different ones down below but thi is by no means a comprehensive list. So feel free to add more, or rather tell me to add more xD.
I've grouped them into a few large sections. Rock, Country, Pop, Hip-Hop/Rap, Jazz and Classical music. I also added a fusion section since a lot of these sometimes... mix. Especially rock.
They only requirement is that they're students at either Uni, HS or the MS.
