PBS is the best. This is an amazing show on global music. There are only two hour-long episodes, one aired in 2010 and this one just a couple weeks ago. You can watch both in full here.
Episode: Sound Tracks, Episode 2
In Episode 2, see how folk singer Julie Fowlis is leading a revival of Gaelic culture from the Scottish Highlands. Join African singer and activist Youssou N’Dour as he tries to run for president of Senegal, and watch jazz superstar Wynton Marsalis on the road in Chicago with his orchestra. The show closes with a “global hit” performance by Of Monsters and Men, a young band from Iceland.
