I don't know how long I've been trying to find it but it feels like forever, and searching for the battle of the bands trope and the braces stuck together trope wasn't any help either. I finally thought this morning to try looking up movies that feature models of buildings because I remembered the tall record store model rising up through what was there before.

My memory of the building scene was surprisingly accurate, though I didn't remember the explosion part. My memory of the girl was flipped, and she walks onscreen in the movie, whereas in my memory, the scene cut to her. She was also very casual in the movie and lovestruck in my memory.
It's such a huge relief when one of these decade-plus mysteries is finally solved.
