I know it’s probably been a while since you picked up that plastic guitar and shredded to some Lady Gaga on Rock Band 3. 5 years after the release of the original Rock Band, the once thriving user base is quickly dwindling as everyone is trading in their hair metal wigs and drum sticks for M16s and military fatigues. Harmonix, the creators of the revered music series, knows this and is trying to bring you back to their baby, if only for one last encore. Last month, Rock Band got a much needed shot in the arm with the very satisfying Rock Band Blitz. And now Harmonix is begging you to fill up your interactive music library with the largest DLC sale in Rock Band history.
