Guitar Hero: Aerosmith is a complete standalone game, separate from Guitar Hero III. It may share assets and code, but the game has been updated enough to be its own beast. And that beast is the two-headed monster of Steven Tyler and Joe Perry. Right from the opening menu that asks you to "Just push any button to play" while "Back in the Saddle" blasts out of the speakers, you can see that the game is deeply infused with the Boston rockers. Pictures of Aerosmith's Vindaloo studio were used to recreate the insider feel. Joe Perry even selected specific guitars to be recreated for use with certain songs in the game.
