If you're on the lookout for a new nerdy music podcast to add to your subscription list (and who isn't?) why not give GeekDad HipTrax a shot? Hosted by Z. of Hipster, please! and Ken Denmead, the podcast is part of the Geekdad network, which is in turn part of Wired.com - ooh fancy. The show features all sorts of geeky music handpicked by Z. himself, and is a great way to pick up a few new favourite artists.
The latest show has an 'instrumental' theme with music from Atari artist, Army of 2600, jazz VGM cover band, The Runaway Five and nerdcore rapper, Antisoc. There's a whole backlog of episodes to check out as well as the show has been running for nearly a year now.
