I was just exploring some music that a friend exposed me to a few months back and came upon this website of the choir Scala. They are a girls choir from Belgium who have traditionally sung pop songs a cappella / just piano accompanied. Great sound and great arrangements. So the website offers their latest album as a free download. Sweet.
Then, right around the same time, I discovered k-os was coming to Calgary on his rapidfire cross-Canada Yes! Karma tour. Turns out they are free concerts. So I went. It was an optional donation deal. If you donated something, you'd get a free CD of his latest album remixed by fans. It was a great show and a friend even caught me on the road on the way for a ride.
Cheers! to FREE music!
