'We would love for this music to make our fans feeeeel something, for it to stir some sh*t up inside of them, whatever that may be,' says singer Karen O. 'SO much feeling went into this record, it was the rope ladder thrown down into the ditch for us to climb up and dust ourselves off. I hope others can climb up it too; we're excited to share the good vibes.'
