I can’t even describe how amazing Garageband is. It’s lets you record almost anything. And it sounds good! And it’s free! And easy to use! And it has basically all the guitar amps and pedals in the world. And real professional musicians use it to record real music. And it works on the iPhone and iPad.
I just recored a punk-inspired version of Bruce Springsteen’s No Surrender with it. I sang (yikes!) and played two guitar tracks, Drums were compliments of Garageband. It took like half an hour. I mean, what the hell?!?!
Here is Steve Jobs introducing GarageBand in 2004. “Garageband is a major new pro music tool. But it’s for everyone.”
And here’s an interesting list of milestones for Garageband.
