Yes I know it's from mathematics/science, but it does sound like a band name or like something from a sci-fi movie

“Our Lawyer Made Us Change the Name of This Song So We Wouldn’t Get Sued” is the first song from Fall Out Boy’s first album, From Under The Cork Tree.

This is a reference to that. My first guess is they're a FOB cover band

The Scottish indie rock band Biffy Clyro have a song named "The Captain", which has the following lyric

Help me be Captain of, these crooked disguises, I won't show what's underneath, it's time for surprises

I dunno if they'd be a Biffy cover band, or if they'd just be referencing the one song

Was an accidental spoonerism I said, and then went "actually, that kinda sounds like a band name"

Typo made for a great band name.

Taken from something I heard on the weather "and we've a band of rain coming in from the North"
