Jam Sessions has been pretty low-key, comprised of a MySpace page, uninspired print ads, and a bevy of videos showing real artists using the non-game to play fake guitar.
Off the charts, then, are New Zealand's excellent television spots for the title, which emphasize how having Jam Sessions in your DS repertoire can transform you into an instant rockstar. According to the ads, being an instant rockstar involves hitting on your buxom aunt, and cursing out your mum for baking you the wrong birthday cake. Honestly, the things those New Zealanders can get away with on television!
If we haven't made it abundantly clear, these videos are definitely not-safe-for-work material. Catch all the raunchy, raucous action after the break (and not a single shot of gameplay, either!).
