Composer Kevin Kiner (from The Clone Wars) returns for Rebels, and they debuted the show’s theme today at WonderCon. They also showed a clip of Hera and the Ghost in action, which you can see above.

UPDATE: There’s a new interview with Kiner on Hero Complex, and a writeup from StarWars.com that also gives us a better look at all the concept art. And Kiner shares some new music in a second video: Is it the theme?
