Mike Post is the multi-Grammy-winning composer behind some of the most recognizable TV theme songs of all time, from “The A-Team” and “Magnum, P.I.” to “Doogie Howser, M.D.” and “Law & Order.” Now, Mike is back with new music — but not for the small screen. He’s released a bluegrass and blues record, titled “Message from the Mountains & Echoes of the Delta.” He chats with Tom about the record and his incredible career in music, including how he came up with the famous dun-dun sound on “Law & Order.”

Plus, the singer-songwriter Joel Plaskett is breaking some new ground with his latest release: a spoken word performance of a poem called “The New Joys.” He tells us the story behind the piece and what made him want to explore poetry.
