ECM has recently become available on streaming platforms, but the label acts quite aggressively against YouTube uploads of its music, so you’ll either need to use a streaming service or seek out the physical disc. However, I think that releases on the label like the Christian Wallumrød Ensemble’s The Zoo is Far or Vassilis Tsabropoulos’s Archirana would serve as good examples (just two among myriad) of how certain forms of jazz exist quite apart from traditional American expectations.
