How They Heard It – Blue Note Records and the Transition from Mono to Stereo
LondonJazzCollector
Adventures in collecting "modern jazz": the classical music of America from the Fifties and Sixties, and a little Seventies, on original vinyl, on a budget, from England. And writing about it, since 2011. Travelling a little more widely nowadays, and at lower cost, but still 100% vinyl
