Big Ears, Knoxville's funky four-day kaleidoscope of a music festival, is bringing back some past favorites and expanding its bluegrass and jazz offerings.

The March 22-25, 2018m lineup was announced Wednesday morning.

Weekend passes go on sale Friday, Nov. 3. You can learn more here.

Knoxville music champion and festival founder Ashley Capps said in a news release that a "deeply spiritual thread" emerged during planning for next year's event.

"Perhaps most importantly is a very dynamic interaction between the global – the internationally acclaimed artists – and the local – our own indigenous culture and sense of place and community. That’s especially exciting to me," his statement reads.

Capps said the character and culture of Knoxville - and East Tennessee - also will be on prominent display next year.

The festival, launched in 2009, tends to draw an international crowd of critics and fans.

Jazz and bluegrass will have a higher profile. Artists will include Medeski, Martin & Wood, frequent Knoxville visitors.

Other artists include Milford Graves, Roscoe Mitchell and Nels Cline, the Wilco guitarist who performed in 2017.

Bluegrass acts set to perform include Bela Fleck, also a frequent Knoxville visitor, and Jerry Douglas, who has played at the Tennessee Theatre with Alison Krauss and Union Station.

Downtown venues that will host Big Ears include the Tennessee Theatre, the Bijou, the Mill and Mine and the Standard.
