Since it’s Penny Arcade Expo weekend, Harmonix has announced that a special PAX Pack is coming up next for Rock Band. And that’s not all that’s special about this upcoming Rock Band DLC – all money generated from the track sales will go towards Child’s Play charity.

PAX Pack 1:

• “Skullcrusher Mountain” - Jonathan Coulton
• “Livin’ on the Corner of Dude and Catastrophe” - MC Frontalot
• “Shhh….” - Darkest of the Hillside Thickets

Each track will go for $0.99, while the whole three-pack will set you back $2.99.
