SPECIAL: Today is Union Day, marking the date in 1964 when Tanganyika and Zanzibar united to become Tanzania. We’ll highlight music from some of the great guitar bands from that country, including Remmy Ongala, the Vijana Jazz Band and more; showcase groups from Zanzibar, including the Culture Musical Club performing with world-blues artist Taj Mahal, and the century-old Ikhwani Saffa Musical Club; and conclude with a lovely piece called Tanganyika from a 1950s album of the same name from the Buddy Collette-Chico Hamilton Sextet.
