Wired blog Game|Life has up an interview with Alex Rigopulos, CEO of Harmonix (original creators of the Guitar Hero series). They're finishing up work on Guitar Hero for the 360, and then they're moving on to bigger and better things. Chris Kohler had the chance to speak with Rigopulos about that next step for the company. They touch on topics like downloadable content, the awesomeness of the whammy bar, the end of Harmonix's relationship with the extremely popular music-game series, and why people just can't agree on music. Says Rigopulos: "People's taste in music varies. Massively. And music that you love, I might think is garbage, and vice versa. And it's really hard to assemble a single soundtrack that's going to have really broad appeal... [with Guitar Hero 2] we got from the metal community was that they were totally psyched that we were giving them the real goods. And a lot of other people who were Guitar Hero 1 fans saying, well, there are more songs in Guitar Hero II where I just wanted to turn down the speakers."
