The theme is (or is supposed to be) a race against the clock. So many beer podcasts cover the interviewee's background and broader range of topics. Time Crunch is meant to just hit on 1 topic, with someone who is knee deep in it. I tend to pick things that I know at least something about, so that I can hold a conversation. For example, I know nothing about yeast, so you're unlikely to see an episode on that because I like it to be more conversational.
So I'm thinking like the beginning of the show 60 Minutes or "24" with a few ticks of the clock or timer, blending into a fairly high speed tune that can blend into me say "Hey Everyone, welcome to Time Crunch, today I'm joined by...". I'm open to different styles, but how about techno
