Her story

Riff started life as a heart in a school band, keeping time on the drums at a steady 72 beats a minute. One day the bass player's heart went into atrial fibrillation mid-song, and Riff noticed before anyone. She has worn headphones ever since and listens for skipped beats everywhere: in music, in conversation, in the queue at the coffee shop.

Nothing irritates her more than a drummer who rushes.
