Run by a Canadian called Brian Sword. Which alone is pretty metal.
Just check out the episode list to see the amazing list of interviewees: http://thedoublestop.com/episodes/
I've been streaming from Soundcloud, easy peasy, even for a technophobe.
There's a fair 80s/90s hard rock slant going on here, which I of course really dig. I found the podcast by accident googling for interviews with Joey Tafolla and was riveted to his tale of trying to make it as a Shrapnel shredder.
The interviews with producers/engineers were particularly interesting for me to listen to, as they told the tale of working on some of my favourite albums with my favourite players from an entirely new angle for me. I hooted quite a bit at Bob St. John's talk of how difficult Nuno is, for example.
These interviews are flipping awesome.
I love the Joel Hoekstra, Richie Kotzen and Greg Howe episodes. The interviews of them give way more insight then probably ever recorded. Amazing to hear how they all got where they are. Brian does a great job going throughout their history.
