This is the Go!Team, who I learned about years ago from Ad Boy (the boy who literally broke my vagina. It's fixed now, but the story is funny as hell).
And this is a little interview with Ninja, the lead singer. It's just so cute and charming I had to include it.
I'll be shaking my ass this weekend at Honk!Fest to the tunes of radical marching bands. Weird, yes.
