I'm surprised that nobody has mentioned the always-interesting fRoots Radio , which seems to showcase all the stuff that the likes of Andy Kershaw and Charlie Gillett used to play, that Ian Anderson played on the BBC World Service, and fills in the holes that Mike Harding and Late Junction can't always reach. It has reliably shown up once a month for the last decade or so as a podcast or stream, with an admirably knowledgeable minimum of presenter chat.
