KAI RYSSDAL: Over the holidays a lot of us are probably going to hunker down with our families, do some quality hanging out, play some board games, maybe watch a DVD. Sad to say, that would be sooooooo last year of you.

This Christmas power chords are the new bonding mechanism. The video music game Rock Band 2 is one of the hot gifts this year. So we're going to reprise a segment I did last year about this time with our gadget guy, Kevin Pereira, from G4 television, and the original version of the game. A disclaimer before we roll this tape: I really can sing better than this.
