Never heard of Briztronix. The few seconds I was able to hear of that song sounded pretty good.
I've heard of Wax Tailor and Nujabes but really aren't familiar at all with their work. The very little I've heard from both artists I liked a lot, though, from what I remember. I heard somebody playing Wax Tailor in a local pizza joint once a few years ago, and just very recently my co-worker was playing some Nujabes. It was kinda weird cuz I had never heard of him until he died, and it was right after his death that my co-worker played some of his stuff at work.
