I hope this isn't spammy, but I want to share a new project I've begun with you. It's a slightly offbeat podcast about the history of sound recording, and I think some of you will enjoy it (if you don't I don't know who will!).
It's something along the lines of what you might call a history of ideas or a cultural history.
I'm up to episode 4 at the moment. The podcast is called : Noise in the Groove: noiseinthegroove.com
Though, at the moment I'd prefer if you find me through iTunes as I'm trying to spread the word a bit.
