I'm surprised no-one picked up on that Guardian best folk albums of 2021 someone posted up the thread: 7 out of 10 of the albums are wholly or partly traditional music, and of the others, you can hear the influence of at least three different traditions on Yasmin Williams' brilliant Urban Driftwood.

I'd contend that outside of the folk club scene, there's still more rumblings in the undergrowth than you'd imagine. Over the last couple years I've heard great albums of traditional music from (off the top of my head) Burd Ellen, Green Ribbons, Jack Sharp, Jake Xerxes Fussell and House & Land. There's more to add to that list. Also great contemporary music rooted in folk traditions by players like Henry Parker and Jim Ghedi. Happy to post some Bandcamp links
