A Musician Called "Dedekind Cut"

I was looking through LA Weekly, and I did a double-take when I saw that some musical artist known as "Dedekind Cut" is performing soon in LA.

I hope the music is rational.

The new EP, by the way, is called "The Expanding Domain" (for real).

In case you're interested, here is a link to the Wikipedia entry for the mathematical version of a Dedekind cut.
