Best Coast are so deep into the Best Coast Zone on new album California Nights that it can be hard to hear the subtle adjustments that make their sound shine that much brighter. Their sound is cleaner and more confident than it’s ever been. And that was in evidence last night, when Bethany Cosentino and her beefed-up band did musical-guest duty on Conan. Below, watch them knock out the shimmering, twinkling pop-punker “Feeling OK,” looking like they absolutely belong on TV.

California Nights is out now on Harvest.
