Paying homage to Malian kora master Toumani Diabate who died this week. Such a sad loss. Also to English blues legend John Mayall, also gone this week. Previews of Vancouver concerts by The Decemberists, Molly Tuttle, and Robert Plant and Alison Krauss coming soon. And a feature on this weekend's Mission Folk Festival. It's SOCAN week, too, so lots of Canadians in the mix
