You should both check out WNYC'S "On The Media." It's NPR style, but every interview you hear is a 40-60-120 minute interview that's been boiled down to 8-10 min for the show. It's truly bespoke radio in that way, so they get to cover the issues at the core of something. It's my favorite show week to week.
In GA, we've got Political Rewind, which is similar and also fantastic.
It's also a simple formula: find an expert in the field who's also a halfway decent host, then invite guests who work in the professional and balance their biases against each other.
On The Media is fantastic. It's really hard to find succinct sources that don't totally misrepresent their subject, and they do an impressive job of it.
