Music: not quite as good as a typical TMBG concert (too many educational songs). Crowd: more interesting than a typical TMBG concert (lots of kids in costumes). Overall it gets a thumbs up, though I imagine it must have been a little weird for Nikolai and Kim since this was the first time they've seen Them in concert. Whereas I can distinctly recall three prior concerts, so this is at least my fourth time—I think fifth, actually.
Also, it took longer to make this userpic than it did to write the post.
