Yes, yes, I know it should be "411," but whatever. It's the best I could do for a headline. It's been a long day. But this week, the Rock Band Music Store adds a three-pack from 311, apparently a band that has long been requested by Rock Band fans.
The "311 Pack 01" contains "Down," "Beautiful DIsaster," and "Amber." The pack will run you $5.49, or you can buy the songs individually for a couple bucks apiece. "Beautiful Disaster" and "Amber" have keyboard parts, and "Down" is the one with the optional $.99 Pro Guitar and Pro Bass upgrades.
And as always, the DLC is also compatible with Rock Band Blitz, and during the first week of release, playing any of the songs from the "311 Pack 01" will net you double Coins whenever you play them!
