The Strokes treating a Hollywood gig like a proper premiere by debuting fresh material live before anyone's heard the studio version. That's either admirably confident or gloriously reckless, depending on how the song lands, but it's exactly the kind of thing that reminds you why people still get excited about seeing a proper rock band do their thing. If you're a Strokes devotee or just someone who appreciates artists willing to take a risk with new material, this is the sort of moment worth keeping an eye on.
