I've not watched a lot of JHS video's (didn't even finish the Bad Monkey) but one came up on the YouTube algorithim which I listened to in the background. At the end he suggested checking out Barr Brothers, Sleeping Operator
A couple of YouTube videos later and this 35 minute live show came on and i'm blown away. I'm not sure how to describe it, an ambient americana? Slide guitar, banjo, harp, double bass creating an amazing sound. There's five minutes of chat in the middle but worth hanging on for the second half.
Are there any other suggestions from JHS you've taken up?
