Tech Podcasts
1Song Exploder can be pretty good in that vein. A lot of talk about how songs came together, what was highlighted in the mix and why, what got left on the cutting room floor. Also, talk about songwriting and inspiration. Not 100% tech nerd, but good for recording folks. Sound Opinions is more rock crit than tech nerd, but it can have interesting focus on songs and albums. Recording Studio Rockstars has been going strong for a while and definitely focuses on engineers and producers more than musicians. There was another one I liked alot that was short run from the drummer for Galaxie 500. It was a Radiotopia presentation, so you might be able to find the old episodes on their site. It only ran for a few episodes, maybe 5 or 6.
