I just listened to "Good Times, Bad Times" and that drum part is pretty insane. Page's comment makes a little less sense.
I think White is pretty on target. It is kind of sad that kids have to learn about music through plastic instruments and timed button prompts. I learned about music in middle school, and high school by playing the trumpet. There are venues for kids to learn music, we teach it in the school system, a great way to get more kids to learn about music would be to fund that better. You learn a lot from actually playing a real instrument (patience, discipline, etc.) and you learn none of that from the plastic ones. There's a lot to music, and while music games can help you appreciate it a bit better, you can appreciate it so much more if you take the time to learn an instrument. And to the people who complain "I have no musical talent". Music isn't some innate ability, you've got to learn it, it's a different language, and you have to use an external "voice box" but you can learn it, it just takes a lot of time. Listen to the early White Stripes albums, and then listen to the later ones. You can hear Jack improve, Jack White doesn't just posses this ability, he is learning and crafting it. Page didn't start out quite as awesome as he became, go listen to the Yardbirds.
Guitar Hero doesn't come anywhere close to a true musical experience. When I play guitar with a group of people and we all click into a groove, and everybody is rocking full throttle, its a semi religious experience. I get a high from it. When I play guitar hero I'm just going through the motions. There are better ways to bring music to kids, hell, there are better ways to bring music to everybody.
That block of text said, if this watered down version of ambrosia is the best people can get, then I guess thats something....
