Australian music historian, author and longtime Billboard correspondent Glenn A. Baker has died aged 74. A prominent and flamboyant figure in Australian media, he helped document, promote and shape the country’s popular-music culture across radio, television, publishing and the record industry.

Born in Sydney in 1952, Baker left school at 15 and later contributed research that helped establish youth radio station 2JJ, now triple j. He managed Ol’55, co-founded Raven Records in 1979, wrote 17 books and sleeve notes for more than 600 albums, and served as Billboard’s Australian correspondent for over 20 years. His collection of more than 80,000 music items, including over 50,000 LPs, was auctioned in 2024; his son said he had been unwell and had suffered a stroke.
