Next week's Rock Band Store update is gonna be a treat for grunge fans as a Nirvana three-pack is on the way. For those whose musical tastes run ever further back, there's a Night Ranger pack for you as well. Details past the jump.

You've probably seen the ads on the malls and stores, but just in case you didn't want to take a closer look then, you can do so here. MTV Games and Old Navy have agree to join up and give you a different kind of stuffing this Thanksgiving. There's quite a lot of offers on this one, so if you have hoodies and Rock Band in your plans, be sure to read up.

A five-song AFI track pack is coming to Rock Band 's in-game music store next week along with one from '80s all-female band The Bangles. Handheld rockers are also getting two new tracks; one each from Dead Kennedys and Sleater-Kinney.

Brother/sister (no, not really) duo The White Stripes will be making their Rock Band debut next week via a track pack featuring three of their songs. For the handheld rhythm gamers, No Doubt and Dropkick Murphys are also on the way to Rock Band Unplugged's in-game music store.

Harmonix has just released a patch for Rock Band 2's Xbox 360 version that adds support for wireless mics, background downloading, and an audition mode for Rock Band Network, among other things. A PS3 version of the patch is now undergoing the certification process and will be out ASAP. There's no word yet on a Wii patch, however. Hit the jump for the patch notes.

The Gorillaz will be headlining next week's Rock Band update with three songs being made available as DLC for the game's PS3 and Xbox 360 versions. The Wii version is also getting its own update in the form of eleven tracks taken from the Rock Band back catalog, while Rock Band Unplugged will play host to a pair of new Iron Maiden songs.

Pearl Jam is getting their own Rock Band title, apparently, and they're building up some early hype for their upcoming Rock Band game by releasing their new album, Backspacer, as downloadable content on the same day the album hits stores.

MTV and Harmonix are opening the doors for user-generated content on Rock Band via a newly announced utility called the Rock Band Network. This essentially gives artists and labels the chance to upload their own tracks and, if approved, get them released as downloadable tracks.

They heard us crying loud... I can hear Billie Joe Armstrong singing "When I Come Around" while I'm typing this down. Growing up to the music of their Dookie album has that kind of effect. Anyway, as previously announced, Green Day is gonna make their July 7 schedule into Rock Band 2 (Xbox 360, PS3, Wii, PS2), for the Wii version at the very least. "When I Come Around" may not be in the first batch, but I'm still hoping that the Dookie album will have its day.

Rock Band will soon come in a shade of Green. With a quick announcement, Billie Joe Armstrong, Mike Dirnt, Tre Cool, and the music of Green Day will be adding classic and new tracks into the Rock Band Music Store. More after the jump.
