EA and Double Fine Productions have already labeled October as "Rocktober," with Brütal Legend set to hit retailers.

They've also announced that gamers can get an early taste of this metal-inspired game starring Jack Black this September 17.  The demo will only be available if you've pre-ordered the game though, according to the official blog, along with an in-game guitar inspired by Tenacious D.  Here is the list of participating retailers provided:

“We just couldn’t wait,” said Tim Schafer, President of Double Fine Productions. “Villagers have surrounded our offices with torches, demanding the game. So we’re releasing a demo and hope that this taste of metal will keep the mob at bay until Brütal Legend comes out this Rocktober.”
