What are the demographics of the high school where you are going to be demonstrating the system?
You need to meet your audience where they are and play music they enjoy. A specialized high school that studies music vs a typical public internment camp that passes for an education will like different music.
And asking a bunch of old White and Asian dudes, with the two old black ex military guys) stereotyping us from who I saw at the one audio show I’ve been to) is not your sample.
I’d recommend a couple of tracks Best of Queen (still culturally relevant and some excellent recordings to show off a system) and to show bass something like Lourdes “Royals”.
And neither of those are particularly relevant to the under 18 demographic, but great recordings and they will know them. Remember it’s not music you enjoy, but they enjoy.
