Breaking its tradition of releasing new downloadable content weekly, Harmonix sent out word that this week’s DLC for Rock Band - the entire album “Moving Pictures” by Rush – has been delayed due to an unspecified “technical difficulty.”

“There is a technical difficulty that is being worked out,” wrote community manager Sean Baptiste on the game’s forum. “I’ll alert you when it is all clear.”

No release date is being offered for the album, which will retail for $11 on Xbox Live and PlayStation Network.

Releasing yet another full album for Rock Band, Harmonix announced that the next album would be “Moving Pictures” by Rush. Available on Xbox Live and PlayStation Network next week, the album will cost 880 Microsoft points ($11) and will include the following tracks:

1. Tom Sawyer (Original Version)
2. Red Barchetta
3. YYZ
4. Limelight (Original Version)
5. The Camera Eye
6. Witch Hunt
7. Vital Signs

More albums are slated to hit the game soon.
