Chiaroscuro is a post-rock band from Indiana that I know nothing about, other than the fact that they toured with This Will Destroy You.
cssc is a one man show brought to you by Erik Rodriguez of Chesapeake, Virginia. Armed with only a laptop and a MIDI controller, he creates some great electronic post-rock. He has a bandcamp page, where you can listen to two of his albums for free.
