Colin Marshall talks to Laurie Brown and Andy Sheppard, host and producer, respectively, of The Signal on CBC Radio 2. Since debuting in March of 2007, the program has evolved to provide a highly distinctive listening experience that offers two skillfully-curated hours of late-night contemporary music to listeners across Canada \u2014 and, via the internet, the world \u2014 that\u2019s neither predictable nor easily genrefiable. Brown accompanies Sheppard\u2019s unusual sonic selections with commentary that\u2019s long impressed fans with its friendliness, intimacy and wealth of odd stories.
