At a community-run event in Seattle following PAX Prime, Harmonix announced the Rock Band Road Crew program. Road Crew is a new program designed to engage with and reward the most passionate folks in the Rock Band community. It's basically a rep program. If you are selected you get a Rock Band 4 Band-in-a-Box Bundle on pre-release and are expected to act as an ambassador to get more people involved in the game by hosting and reporting on events. The more events you host and better you get new people involved, the more swag you get, including DLC, e-magazines, gift cards, and more.
More details about the program can be found on Harmonix's website. The program is open to residents of the 50 United States, DC, and Canada (but not Quebec). Sorry Quebec.
