This is a very original sound, infectious groove, fast tempo, interesting lyrics with a strong melody. And these breaks are super; the groove ownership from the drums feels like a track from Phoenix. The whole vibe is a party, and really high on energy.
Those clean electric strums do not prepare you for that stick-heavy drum thing; and that does not prepare for the hook. No one can be ready for that. All you can do is turn it up.
Also, pay attention kids: that is how you write a bridge.
