Big Indigo fan here. Love their music, hate the politics. That being said, one of the best birthday presents I ever got was a 20 minute (which turned into 35 minutes) online guitar lesson one-on-one with Emily my hubby got for me. She taught me the lead to Land of Canaan and some other picking things. Very nice and very gracious. Unfortunately, Emily’s voice is not the same anymore and I can’t listen to any of the new stuff.
I haven’t listened to later stuff, but they are very talented.
