A collection of old skool hip-hop tracks smushed together with the compositions of Philip Glass. When I was around 9 years old, my mom introduced me to Glass' works (actually, the album Glassworks), and I've been a fan ever since. I forwarded her this link, and she replied, "I wonder what he thinks?" I'm curious, too!
Update: Some folks have reported problems accessing the MP3s today. Reader Josh Berezin says,
It looks like the Philip Glass / Hip Hop mp3s are moving… I pasted the *.mp3 part of the URL into the base url of the site, like this and they seem to be there, though the links themselves don't reflect that yet.
