Harmonix and Child's Play have announced that they're banding together for a charity benefit Rock Band night at San Francisco's DNA Lounge the night of December 9. "Ümloud!" is an all-ages event organized by GameLife's Chris Kohler, Gamehelper's Joe Markert and Telltale Games' John "Seg" Seggerson, and staffed by a number of Bay Area games bloggers, including yours truly.

The party kicks off at 7PM PT and runs through 2AM PT on December 10, with a suggested $10 donation for admission. Everyone who attends will automagically be made eligible for a chance to win some of the many raffle prizes that'll be awarded throughout the night, but those who wish to donate more can sign up for two different "band packages" -- which include reserved songs and the chance to play on DNA's main stage -- at the Ümloud! site.

Proceeds from the event will go to provide toys and video games to children's hospitals nationwide, including the local Oakland Children's Hospital.
