Andrew Gurruwiwi leads the Andrew Gurruwiwi Band in what they call 'Yolŋu funk', a mix between reggae, heavy metal, and funk in language from across the region. Andrew tells us about his music-making, his career as a radio presenter, and explains the stories behind some of the tracks on the band's dynamic debut album, Sing Your Own Song. "He basically invents the rules of jazz. He shows you 'this is how to play a solo, this is how to sing, this is how to phrase, this is how to tell a story, this is how to swing. Ok, this is jazz. And now I'm going to break all those rules.'" - Ricky Riccardi on Louis Armstrong Towards the end of the 1960s Louis Armstrong's performances were hit-and-miss. Plagued by health issues and pushing 70, the veteran entertainer was determined to keep playing, singing and touring, despite calls from his doctors to slow down. But in 1968, with a burst of vitality, he performed for BBC TV with hits spanning his remarkable five decades in music. This included What A Wonderful World, a song that had made him a household name just weeks prior. The concert recording of Armstrong's "last great performance" has been rediscovered, and now released as live album Louis In London. Ricky Riccardi is Director of Research Collections at the Louis Armstrong House Museum and joins Andy to talk about the great trumpeter and why we're still talking about him over 50 years after his death.
