Harmonix has announced a new expansion for Rock Band 4, Rock Band Rivals, which includes two brand new features for the title: Rockudrama and Rivals Mode.
Rockudrama is a “playable rock documentary” for players and their friends to form a bona fide band and star in a fictional, “reality” TV show called Beneath the Tuneage. The show appears to have everything you would expect from a reality show, including a narrator, live interviews with people your band has impacted, and clips of “ridiculous experiences” from your band’s rise to fame. The Rockudrama will also introduce new venues, Rock Shop items, and gameplay challenges. 
The announcement trailer for this part of the Rock Band Rivals expansion is below.

Rivals Mode is a new form of competitive multiplayer that will pit your Crew against rival Crews in online weekly challenges and leaderboards. Rivals Mode will include Quickplay, Rockudrama, or Shows mode, so anything your band or just you prefers will contribute to your Crew’s progress. Harmonix also already has a list of preorder incentives for the expansion, which includes an in-game cheeseburger shirt and golden sword guitar. The following tracks will also tack on to any preorders:
