Itty bitty Bleachers are just too adorable.

I go back and forth about how I feel about Bleacher's debut—sometimes it feels right and sometimes it feels wrong—but after seeing them lie this summer I have zero doubt as the question whether to Jack Antonoff's enthusiasm about the music he makes in sincere. It absolutely is. So I almost squealed like a little girl at just how he took the band's live set up to—or would that be down to—the next level with this appearance on Conan.
