DLC Week April 22nd: First full album- Judas Priest! - Rock Band - Forums
Its nice to finally have the full albums coming, but people have been screaming for Nirvana and The Who for so long that this seems just a bit disappointing.
RockBand.com says that there will be a lot more info coming in the next few weeks regarding The Who and other complete albums.
