Can I play European DLC in Rock Band on a U.S. console and game?
No. Rock Band content is region-specific, so your game, console, and DLC must all match the same region.
If you download DLC from a different region, it may not work or be playable.
This applies to all regions, including Europe, the United States, Asia, and Australia.
If you purchased DLC for the wrong region, contact your console’s support team for help with your purchase.
