Some call it a podcast, while others call it a radio broadcast segment ported to the web. In either case, the estimable Echoes radio show has posted an interview, including musical interludes, with fourth-world trumpeter Jon Hassell. He talks about the increasing prevalence of non-western touches in popular music, and riffs on the correlation between so-called fusion cuisine and his own brand of global-blender ambient jazz. A search for “Hassell” on the show’s website, echoes.org, yields a null return. But you can download the MP3 directly here, and subscribe to the Echoes podcast here.
