Continuing our series on Rock Band, we are taking a look at the new songs Harmonix has made available for download today. If you would like to read about previously offered downloadable content, please check out our first review published last week.

We really appreciate the comments we received last week, many of which brought up an interesting point about the positive or negative impact Rock Band could have on musicians or potential musicians. Before we get into the new content, we'd like to address this.

As some people have mentioned, the guitar is very dissimilar from an actual guitar. In spite of the fact that you certainly could learn bad habits, it is hard to confuse the Rock Band guitar from anything but a glorified controller. The drums, however, are quite different. In fact, the kit is very similar to one of the first Roland electronic drum kits I played, with the obvious and frustrating exception being that you can't reposition the pads.

Teaching drummers poor technique is certainly a potential pit fall of Rock Band for those gamers who would either like to get into drums or already play. But it really isn't much worse than someone setting up one of those old Roland kits with the intention of playing along to the radio as their method of teaching themselves. In either case, those who are serious about drums will take the time to learn some proper technique.

Of course, Rock Band's short comings have forced us to pose an interesting question. What would we want from a game that could also potentially be used as a real teaching device for instruments? Answering that for guitar is difficult short of making the controller into something more like an actual instrument. But since the drums are already so close, we can easily tackle that one.
