For actual content, here is a portion from the Nihon album by Method of Defiance, one of Bill Laswell's (a jazz bassist) many projects. You may find the album on Spotify. If ya never heard of MoD, they are jazzy ragga dub drum n bass. Guy Licata is a sick drummer, he can do breakbeat drumming like a drum machine. I love the distorted trumpet provided by Toshinori Kondo. And damn, the world lost an amazing keys player when Bernie Worrel died a few years back. Worth checking out Praxis, another Laswell project, if you want to listen to jazz metal.
