What she plays fits the song and it doesn't seem to suffer too much for not having blazing fills or subtle nuances on the kit. There's not a single moment where she's trying to slip in any pet licks or tricks. Like Phil Rudd or Mr Peace and Lurve she just plays the song with no bull and leaves space for the music to happen. That gives Jack a ton of freedom. No wonder he likes working with her.
