Illuminate. That's the title of the program that Nomi Dance and Chicago Repertory Ballet will present at Chicago's Athenaeum Theatre (Saturday, October 28th at 8pm), and it's a title that's likely to be a good synopsis of the kind of experience that their audience can be looking forward to. These are two very accomplished dance companies -- both of them bright, both of them bold, and each of them likely to shed more than a little light on the artistry of the other.
