Billy has a radio show on Friday afternoons at WFMU on the East Coast which you can listen to online. He also still runs Hip Hop Slam and writes for the Amoeba Records blog.
He's doing well...living in NY and deeper than ever into music. He works @ WFMU radio in New York http://wfmu.org/ and does a weekly radio show (http://wfmu.org/playlists/BJ) along with some blogging for the station. He also is fronting a large crew called DJ's of Mass Destruction and still putting together his DJ series projects under his HipHopSlam label (http://www.hiphopslam.com/). I been in contact with him quite a bit lately so let me know if you need his e-mail address. As you probably know a real stand up person who loves where he came from.
I still have a bunch of the FTB tapes. Great stuff on those.
I also have a video interview he did with The Click at The Music People in Oakland right before Game Related dropped. It's on a fuckin' VHS. Gotta get that converted so I can post it.
