Saw the Head and the Heart last summer at Osheaga and they did not suck, Tom.
I'm sure they thanked you so much, from the bottom of their heart, for being such a great audience. I'm sure they told you how deeply moved they were and how much it meant to them that you were there. And then I'm sure they did more Coldplay-esque folk pop.
Who do you consider folk on the Stagecoach lineup?
Florida Georgia Line, duh.
Stagecoach is not necessarily deep on it, but Shakey Graves, Sarah Jarosz, TBT, Shovels and Rope, Spirit Family Reunion, Hurray for the Riff Raff, and Jason Isbell are all great acts heavily influenced by the old folk legends.
Also, I'd like to reaffirm that the Head and the Heart are very solid live and seem to enjoy what they are doing. Their set at Outside Lands last year was pretty damn magical.
Shovels and Rope play some pretty rootsy folk music, but also have some rock songs. Also they were awesome at Coachella last year (but i've read your Saturday rant in which you didn't like them). Trampled by Turtles?
AC/DC and Steely Dan? Why not just get a Don Henley project on the poster so my dad can bring his R/V, his fourth wife, and make a day out of the damn thing?
