I think I've seen The Arkestra about 4 times now. Maybe 5? They're fucking brilliant. I had to Google and check but Marshall Allan is still alive, 96 years old! He was leading them all the times I've seen them play, and he's still on the fags. You can catch him between sets having one outside. There's something about a big band with loads of brass live that's incredible, especially when they trade between dissonant noise and the more throwback big band jazz moves (has a pre-war feel to me).
When I first saw them, they felt like a real throwback to a lost era - the 60s, radicalism and communal living, black power and so on. But weirdly, to me it seems like that moment has come back around again. Not just with BLM and the protests against George Floyd's murder but in music. Artists like Angele Bat Dawid, Damon Lock, Matana Roberts - all of them owe a direct debt to Ra. That the Arkestra have simply just kept on trucking has directly contributed to this, I'm sure. All the above must've seen them live.
