Bands on the schedule which are worthy of note so far are:
Flatfoot 56 - Punk rock with some folk influences. The rowdiest show I've ever seen.
The Chariot - Craziest metalcore band I've ever seen.
Paper Route - Very spacey, trip-pop; New stuff is said to be "dream-pop"; Pretty theatrical band.
White Collar Sideshow - Very theatrical, experimental drum and bass bands, led by a steampunk.
Denison Witmer - Great, melancholy folk in the vein of Elliott Smith.
Daniel Amos - Experimental 80's psychadelic prog-rock reunion show.
Psalters - Crusty ethno-anarcho-folk-punk with Balkan, Middle-Eastern, Appalachian and Black spirituals influences. Mind blowing.
Ben + Vesper - Indie/folk married duo (awww...how sweet); good friends of Danielson.
Brooke Waggoner - Singer/songwriter with awesome string arrangements and some pretty unique piano stylings; more indie rock than folk.
Destroy Nate Allan - Acoustic-Punk duo/couple who are very entertaining and flail and shout a lot; fantastic people
Lust Control - Very sarcastic punk band from the 80s which sang a lot about sex. ex. "Masturbation, is artificial sex!"
Listener - Spoken word on top of instruments; Like a one-man mewithoutYou.
Massive Scar Era - Honestly, this nu-metal band is not great. But they're coming all the way from Egypt and have a female lead singer, and have some notably middle-eastern influences in their sound, so I'd be entertained.
Sexually Frustrated - Today's response to Lust Control; More sarcastic over-the top punk.
Songs of Water - Experimental prog-folk collective, mostly instrumental and with heavy focus on beats
Take It Back - Mix of punk rock, slower ranty hardcore, and fast old hardcore
Timbre - Brilliant harpist backed up by a slew of indie rockers.
The Unfortunate - Fantastic indie rock stylings. Nothing mind-blowing, just surprisingly good for what it is.
Any if they end up showing up or getting a slot:
The Soil & the Sun - Band of up to 10 members doing very busy indie rock, with really unique beats;
The Illalogical Spoon - Crusty anarcho-folk, at times very sludgey acousti-core.
Insomniac Folklore - Horror folk with a bit of folk-punk flavour
Seth Martin & the Menders - Anarcho-folk, singer-songwriter style
John Felton / Eternal Soulmobile - Acoustic folk-rock/punk with a playful side
I like how most of these artists know each other, and obtain their backup band based upon which of their friends show up for the fest. Timbre will mostly like be in everyone's back up band.
Any others I'm missing, people?
