Very nice find, tore! I'm still going to bet that 11's uncommon. But this is lovely to see. And yes, I'm hearing 3-3-3-2 here too. But that's def in 11, starting at about 0:45. The drumming at the start is probably too, but it's certainly harder to hear given the rhythm.
I'd venture to say this is 11/8. But that's just a personal preference. It's certainly 11.
