The festival will return to Horning’s Hideout, just west of Portland, for the weekend of August 25-27, with three full days of acoustic music planned.

Yonder Mountain String Band will play the closing set each night, joined by guest fiddler Darol Anger.

Son Volt will perform in an acoustic format, as will Todd Snider, while Danny Barnes will play one of the festival’s only electric sets.

The festival will also feature the first public performance by the duo of Brendan Bayliss (Umphrey’s McGee) and Jeff Austin (Yonder Mountain).

Thile plans to sit in on a number of sets throughout the weekend, in addition to hosting the annual String Summit Super Jam, which has featured such luminaries as David Grisman and Jerry Douglas in past years.

The Summit’s band contest will take place on the first day of the festival, with four finalists competing for a main stage slot on next year’s bill.

Three-day passes are on sale now for $115 to $135 at musictoday.com.
