well indie bands are signed bands. i dont personally know any "unsigned" bands, most minor bands that are native to colorado are signed to local companies and such.
just to list a few, heres some of my favorite indie artists.

Indie is one of my home genres. Loveitloveitloveitloveit. Listing the artists I listen to would take too long, so I am going to post my last.fm . . . I don't have albums for a lot of the bands I listen to, so I have a wider range than is displayed here, but meh, you get a pretty good image from here.
