Listen to the entire interview and session: http://soundcheck.wnyc.org/2012/dec/18/passenger/ Until recently, the British busker-turned-troubadour Mike Rosenberg -- who records under the moniker Passenger -- was an unfamiliar name to American audiences. But that's about to change. This year, the songwriter and guitarist put out his first American release, All The Little Lights, had a song featured in the CBS show Elementary, and has more than 4 million views and counting on YouTube for the song "Let Her Go." Watch Passenger perform "Feather On The Clyde" live in the Soundcheck studio.
