The Rock Band Harmonies Project (RBHP) has been releasing upgrades to official Rock Band songs and DLC since 2012, and has been a proud sister project to C3 since our inception. A RBHP package interacts only with official Rock Band content, does not require Title Update #4, and doesn’t disable online play. Check it out!
This announcement was supposed to go out with the last two weekly song releases, but I messed up and forgot it.
The two November RBHP releases include 48 harmonies and keys upgrades! Featured packs include Going Country 01, Peace Sells, Alice Cooper 01, Spinal Tap 01, Wolfmother 01, and more.
Check out the full list below for more info, or go directly to the Rock Band Harmonies Project site to download these upgrades!
