Rock Band, the stunning new rhythm action game from Guitar Hero creator Harmonix, will give you the chance to polish off a track with your own twiddly guitar lick or skin-beating drum solo. All the note bars will fill with color, and you can bash out anything you like.
Songstrels won't be left out of the noodling madness, though. As a Rock Band singer, you'll be able to "call out the crowd" by ad-libbing or shouting to the audience to bring your fans to their feet. While drummers will also get regular freestyle slots allowing for mid-song fills.
Finally, intriguingly, we've discovered just how the extra fret buttons on the Rock Band stratocaster controller will be used. By changing to these keys, you'll be able to finger tap notes in solos, with no need to strum - although we're fearing that Expert mode will demand you learn to finger tap properly.
Check back here next Wednesday for more on Rock Band, as we'll be revealing the full hands-on details then.
