Beck and Wilco would still be my top choices of non bluegrass/country acts, though both delve into the folky country aspect at times.
I'm always happy with the regular acts of Hot Rize, Punch Bros, Greensky, Sam Bush, and man was Tim O'Briens set fantastic last year.
Of course I'd be way into an old school Leftover set (especially if they reunited with the Apt.)
I've said it many times Jeffrey Lewis and Los Bolts should be given a good listening by all festivarians, and given consideration by PB.
Some links to Jeffrey Lewis music:

and I'd highly suggest getting any of Danny Barnes projects.
Thats all for now. Hope everyones having a good November, maybe we'll see some of you in Steamboat this Feb.
