Do you know any of the other usual suspects in the metal/jazz overlap? I assume Animals as Leaders are widely known now, as might be Norwegian band Shining (not to be confused with the vastly inferior Swedish Shining; I'm talking about the Shining that released Blackjazz)
Less well known are Italians Ephel Duath (The Painter's Palette is one of my all time favs) and Dutch band Anomaly (here is their hard to find eponymous album: youtu.be/FhA88DrK1UY?...)
Then of course there's Germany's Panzerballett and I guess qualifying on a technicality O.S.I.
This is a genre I usually do not like but I'll check these out later thanks!
