Of all the wonderful things we've learned about Rock Band, we were completely unprepared for the bombshell dropped in Joystiq's hands-on with the game. It is truly the best thing we have heard in a long time. Yes, that's right, the microphone not only doubles as a tambourine, it also serves as a cow bell. If you're playing Blue Oyster Cult's "Don't Fear the Reaper," you can bet your booties that you'll be applying some judicious cow bell. Of course, Joystiq's hands-on preview contains much more information, and you really should read it, but it is our job to extract the essence of all that we cover. If there be anything purer than cow bell, we haven't seen it.
