After 275 consecutive weeks of DLC that produced over 4,000 songs, Harmonix is tuning up Rock Band for its final content release on April 2nd. As the once-prominent rock star sim walks up the Stairway to Heaven, its studio will release additional tracks and pro guitar upgrades. This final planned run of new content will include music from unnamed artists who have yet to be featured in the Rock Band series. Sure, this news is a bummer, but not all hope is lost. Harmonix clarified that this isn't the end of the Rock Band franchise as a whole, only its weekly DLC release
