Artist To Watch Ryn Weaver made her television debut on Letterman last night. She performed “OctaHate,” the song that put her on the map, wearing an outfit reminiscent of the video. The hard-to-define “OctaHate” is a pop song at its core, but Weaver’s band rocked it out a bit. Weaver herself gave a vocal performance as frilly as her massive collar, and for the most part it worked. Watch below, and stick around for the awkward hand-holding from Dave.

Weaver’s Promises EP is out now on Friends Keep Secrets/Interscope, and Weaver is playing both Coachella and Bonnaroo this year.
