So this one seems to have slipped thanks to our friends at the ESRB. A new listing shows the Rock Band Track Pack: Classic Rock title. Judging by the title’s descriptions, it looks like Steve Miller Band’s “The Joker” and “Take the Money and Run” will show up to allude to drug use and violence, and Dead Kennedys’s “Holiday in Cambodia” will focus more on the violence part but also offer some choice expletives such as “ass” and even a racial slur. Beyond these tidbits delineated by the upstanding citizens running the ratings board, not much else is known. We will, however, go ahead and agree with Destructoid and say the pricing will be around the $29.99 range with availability on anything Rock Band is available for.
