Owl City 2011: All Thing Bright and Beautiful Tour: Order of the opening acts?

Hi guys. This Sunday, I'm going to see Owl City live. However, I want
to catch Breanne Duren live, but not the other 2 acts. I was wondering
what order the acts play in? (Is Breanne first or last?) Also, what
time should I show up if I want to see Breanne and Owl City, but
nobody else? The concert starts at 6 PM.
