Steve Talbot worked in public TV for more than 20 years before trying his hand as chief fundraiser for one of his own projects. His timing was not the greatest. On the day in 2008 when Lehman Brothers imploded, PBS agreed to back the pilot for Talbot’s Sound Tracks, a newsmagazine-style show about contemporary music around the world. The hourlong debut, which aired in January 2010, got positive feedback from viewers, programmers and PBS, but the recession has hampered Talbot’s efforts to make more episodes of Sound Tracks ever since. He’s still raising money to produce additional episodes.
