Review: While Nat Birchall is naturally best known for his jazz work, he's no stranger to the world of dub and reggae. In fact, "Tradition Disc In Dub" is his second full-length collaboration with roots reggae musician, producer and mixer Al Breadwinner (the first, "Sounds Almighty", dropped in 2018). It's a little more spaced-out than its predecessor, with both Birchall and Breadwinner emphasizing weighty riddims, echoing instrumentation (sax, flute, organ etc.) and the kind of analogue effects that marked out the golden age of dub. In fact, the "golden age" reference is particularly relevant, because while there's plenty of subtle variety on show throughout, it's closer in tone to King Tubby and Lee 'Scratch' Perry's 1970s work than, say, Mad Professor or Iration Steppas. More importantly, it's also superb.
