AC/DC Live: Rock Band Track Pack

Rock Band Track Packs (called Song Packs in Europe and Australia) are a series of supplemental media discs for the Rock Band series of music video games. The packs are developed by Harmonix and Demiurge Studios (earlier packs were developed with Pi Studios), and distributed by MTV Games and Electronic Arts. The track packs are fully functional standalone games and do not require separate Rock Band titles to play; however, on consoles that support downloadable content, the songs from these packs can be integrated with other Rock Band titles.
