Up a set of stairs in a musty Polish wedding venue, 11-year-old Lizzie "Ultrasonic" Newell, wearing a backwards, gold snake-print hat, approached a cluster of five world-famous beatboxers. Their circle immediately absorbed her.

Newell showed off her own plucky drum beats, bouncing along in time. She fit right in here, yet wore a look of shameless admiration on her face. About an hour later, Newell was downstairs in a similarly musty hall with a controller in hand, getting her butt whooped at Super Smash Bros. 4.
