DLC is generally compatible with all Rock Band games. If you don't have Rock Band 3 you won't be able to play the Pro Drum (using the cymbal attachments) or Keyboard parts. Based on other DLC the keys part will be the sax part. I'm guessing they might include some of the violin parts too, depending on what's happening in the song.
This is just about the best Rock Band-related news ever, btw.
