They take the honor of being the only exhibition of showmanship (as compared to musicianship) that I've seen all week.
That bit the singers did at the end of the second-to-last song really made the show for me.
As you said, musically I liked Dosh better. Dosh's closing song (not the encore) was great!
I came for Casket Girls' "lilting voices," but it was impossible to hear the vocals where I was standing. I'll give them another chance.
Another group with good showmanship you might like is the theatrical dance/music performance of Kristal and Johnny Boy.
