I really like this live performance by Grimes. She sits on the floor, twists knobs, taps buttons, and moans into a mic like it was the most casual, natural thing in the world. It looks like you could sit beside her, turn the knobs a bit differently, tap other buttons and you could make a different song.
The years of play, of experimenting and trying are covered in her ease. It’s like watching a great athlete at play on her chosen field.
