Boing Boing's Xeni Jardin reported today that there's a Philip Glass mash-up project on the web called Glassbreaks. It's done by dj BC, whose work I'm familiar with. It's a pretty good set, mixing Glass with hip hop. Sometimes the "Glass" work in the mix is pretty minimal sampling.
I only had difficulty downloading one track, but as Xeni's update notes, you can go to the root directory and get any tracks you have difficulty with.
