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.

Well, they don't use the word jazz. It's Manfred Eicher's German label. Keith Jarrett, for example, has released dozens (100+, I imagine) of recordings on ECM.

...which since the 1970s has had a huge amount of Norwegian and Swedish (and more) musicians recording for the label, and recording sessions are often held in Oslo or Lugano. German headquarters, but more than just a German label.

Keith Jarrett _can_ swing (super hard!) - but he doesn't always - so some of his work qualifies here.
