I did an interview with Geoffrey Grosenbach on his Rails Podcast this morning. It was a fun, interesting conversation. I think Geoff must put in a good amount of time preparing for these things, because he made a connection between Archaeopteryx and Grand Master Flash which was very well-informed. Geoff brought up that Grand Master Flash built his own DJ mixers and considered tinkering with technology to be a fundamental part of DJing. I've known plenty of DJs who didn't know that. I'd forgotten all about it myself. (I think it's in the movie Scratch.)
Anyway, I definitely enjoyed it. Check it out.
