Still not convinced that GarageBand is the killer app that'll revolutionize music production for the masses in much the same way that iMovie made desktop video a reality and WYSIWYG and the LaserWriter spawned a zillion homemade newsletters? Personally, we were sold as soon as we noticed that reviewers of the software were posting links to their first songs, which is as powerful a statement about the app's charm, ease-of-use, and downright addictiveness as any five-star review. But if you need more evidence that there's a musical revolution a-brewin' (you incurable skeptic, you), look no further than the MacMinute article pointed out to us by faithful viewer bRaD Weston.

If you happened to catch presidential hopeful Howard Dean's concession speech after the Iowa caucuses on Monday night, you may have noticed that he got a little... well, "enthusiastic" might be the word, although "Ballmeresque" isn't too far off the mark. Simply put, at one point, the guy starting shrieking. And according to the Wall Street Journal, a 29-year-old named Jonathan Barlow fired up GarageBand, imported the Dean shriek, and soon cranked out a lovely techno remix of that proud moment. "It was the first complete thing I did with GarageBand," he says. "It didn't take more than about 15 minutes."

Weirdly enough, though, he's apparently not the only one to have done this: .Mac user "lileks" (reportedly columnist James Lileks of the Minneapolis Star-Tribune, whom we know better as the brilliant man behind The Gallery of Regrettable Food) posted his own Mac-mixed interpretation of the Dean exclamation in the Public folder of his iDisk; it's called "Yeagh.mp3," and you can download it via his .Mac HomePage. And, okay, when he made his, James actually used Soundtrack instead of GarageBand, but hey, the principle of Easy Music for the Masses still applies, right? After all, there's no reason James couldn't have used GarageBand if he hadn't already had a copy of Soundtrack handy.

So there you have it: music (such as it is) as timely political and/or cultural commentary, all made possible by GarageBand and Soundtrack. A presidential candidate makes a goofy noise on Monday night; by Thursday morning the Wall Street Journal is linking to two different musical interpretations of the squeal, both made possible by Apple software. If that's not a revolution, what is? Here's hoping Kerry or Edwards burps on camera sometime soon; that'll inspire enough GarageBand compositions for a double-CD compilation album. Do we smell a Grammy? Or did Kerry just have chili for lunch?
