Summertime is music festival time. But if you’re looking for a musical blowout in the dead of winter, head to Glasgow Scotland for the annual Celtic Connections Music Festival. This year’s event features two-thousand musicians from the worlds of indie rock, jazz, traditional, hip hop, electronica, country, fiddle music, singer-songwritera and many more from Africa, South America, the U-S, Canada and the British Isles. We learn more about the 18 day event and hear some of the scheduled artists on this week’s edition of Global Notes.
