i suppose that i have been a bit remiss in mentioning this, but my good friend and business partner (chefofcilantro) is now running a local podcast about the dallas music scene (recently featured in D magazine). interesting guests from the local scene abound, and it's an excellent introduction to dallas artists. if you're in the dallas area, or care to learn about some of the great talent from here, then grab their feed:
