Check out Battles. They are mostly instrumental, but they are progressive as hell. I doubt you will hear anything as unique as this. I just saw them in Toronto the other night and I was blown away at how talented these guys are. If they had a singer, they could easily be the next Radiohead (yup I said it).

Also, my friends are in a band named dodger. They have an album coming out produced by Jag Tanna from I Mother Earth.
