At some point during the search for audio, my son — who is well-attuned to my musical tastes after years of car rides to and from school — was concerned something was wrong. He’s currently a junior in high school and big into band (All-State trumpet), so I explained what I was doing and asked him to create some music for the demo. If you check out the default playlist, the two songs by Jay Garcia are his. I’m impressed with the results considering he hadn’t used GarageBand before.
