Making music on toy instruments is tough enough on its own, but that goes doubly so when players have nothing to strum along to. Rush fans have learned that the hard way this week, given that the promised full-album download of the prog-rock act’s 1981 record Moving Pictures did not make it onto the Xbox 360’s Rock Band store yesterday.

The good news is that Harmonix is aware of the issue. "Just so you know, we know that Rush’s Moving Pictures isn’t up yet," said community manager Sean Baptiste on the developer’s official Web site. "There is a technical difficulty that is being worked out. I’ll alert you when it is all clear." The bad news is that, as of press time, Harmonix had not established a time frame for when the DLC will be available.

Rush’s Moving Pictures is the latest full-album download to be added to the MTV Games-published rhythm title. The track pack, which includes such classic rock-radio staples as "Tom Sawyer" and "YYZ," is expected to appear in the PlayStation 3 edition of the game tomorrow.

[UPDATE] The Rush full-album DLC for the Xbox 360 is officially going no where in a hurry. "Unfortunately, due to unforeseen technical difficulties, we won’t be able to release Rush’s "Moving Pictures" this week," said Baptiste in an update to Harmonix’ site for the game. "We’ll be working on it as hard as we can, but it looks like it could be a couple of weeks to fix."

Baptiste noted that Harmonix will be rearranging its schedule to ensure new content arrives this week. The community member promises to have more information on what songs will be added to the game’s downloadable library soon.
