The Gypsy Tales podcasts are good. They're mostly motocross focused but there are a few MTB riders he's interviewed, most recently Loic Bruni.
He's also done interviews with Casey Stoner, Danny Ricciardo and all sorts of other people.
Worth a listen.
They're all around 2-3hrs so it usually takes me a few listens, which is good to make the boring commute to/from work a bit more entertaining.
