Basically, take Guitar Hero and add drums and a microphone and you and up with Rock Band. Thankfully, it is much more in depth than that. It apparently has a rich story mode that isn't as linear as Guitar Hero III and it has online multiplayer!

The neat thing about Rock Band is it can actually teach you to play drums! Yes, it is $170 for the full game (which comes with game, guitar, drums, and mic), but I've played the demo in Best Buy it it is a whole lot of fun. There's already a bunch of downloadable content available for it too.
So, the impression I get (from reviews and first-hand experiences) is that Guitar Hero III is more for hardcore GH players. If GHIII is maybe out of your difficulty setting, then try Rock Band, which seems geared toward the casual/average crowd a little more. For me, that's great. My fiance and I both loved Guitar Hero II, but I'm crappy on the Hard setting and my fiance can barely beat a song on Easy... So, if Rock Band is how they say, both of us should be able to enjoy it more than we did GHIII and we will both get a new experience out of it besides just guitars. She can go pretend she can sing on the mic and I'll go give the cat a headache by pounding on the drums.

Note: They are supposed to release the guitar, drums, and mic as individual SKUs in February so that you can purchase them individually instead of as the $170 bundle. So, if you know you will never perform karaoke, you can just pick up the game, guitar, and drums. Or if you want someone on bass, you can go get an extra guitar starting in February.
