In case you missed it, here is Proper Discord's contribution to Drew McManus's Take a Friend to the Orchestra project. He shares his experiences attending orchestral concerts with non-musicians, and the results are pretty much what you would expect. If the show was good, his guests enjoyed it; if it wasn't, they didn't.
PD explodes (IMHO) the argument that suggests that audience members have to have technical musical knowledge to enjoy musical structures like sonata form. His guests either liked the show or they didn't, and didn't need a technical explanation to justify their reaction. It's like eating out, PD says:
When you’re sitting in a restaurant and your food shows up cold, you don’t care why it wasn’t cooked properly. You just wanted it warm.
