Smashcore is like noise music except it can only be properly appreciated while your car is wrapping itself around a telephone pole, and for some reason Sofia’s mom won’t even let her have the old Camry to try it.

“You hardly even drive it,” Sofia points out reasonably.

“That doesn’t mean you can wreck it,” Mom groans. “You’re not even sixteen!” she sneers. “And all it’s going to sound like is you breaking your neck!” she screeches, over and over, like a broken macaw.

Sofia tries running her bike into a wall with her headphones on but obviously that doesn’t work.
