You can definitely leave Seeger out.

He's just one of the core figures of american folk.

Yeah but I happen to think unjustly.

Anyway, let's talk about the other person you mentioned, who does kick ass, the great Woody Guthrie.

Sufjan Stevens
Iron & Wine
Bob Dylan
Elliott Smith
The Tallest Man On Earth

S'all I got right now.

You're missing Bon Iver i am ashamed of you (for now)

Bon Iver is a snoozefest.

just my favorites (no order):

Pete Seeger
Jeff Mangum (of Neutral Milk Hotel)
Sean Bonnette ( of Andrew Jackson Jihad)
Phil Elvrum (a.k.a Mount Eerie)
Bob Dylan
Spook Handy
Chris Thile (of Nickel Creek and the Punch Brothers, more bluegrass but w.e.)
Sam Beam (Iron and Wine)
Paul Baribeau
Woodie Guthrie

oh! gotta throw in Phil Ochs, he is a close eleventh

you really haven't listened to his music have you?

Just realized my list is pretty cliched. He's some more obscure stuff so I sound cooler

Dr. Dog
Cocoon
The English Panther
Mason jennings
Josh Ritter

i LOVE dr. dog. just saw them at the clear water music festival with pete seeger, arlo guthrie, elvis perkins, taj mahal, and a bunch of others
