Nujabes was a Japanese hip-hop producer and DJ. I think he was most well known for doing the music to Samurai Champloo. He truly made some wonderful music and it's sad to see him go. It seems like most of the RPGfan community is into rock and metal, but I hope some of you listen to or heard of Nujabes.
Here is a statement from his friend Shing02, who Nujabes collaborated with often. http://e22.com/nujabes/
