KETTAMA, The Warren Haynes Incident, Frost Children and Dean Turnley have all been added Live Oak, FL’s Hulaween. As previously reported, the Halloween festival will take place at Suwannee Music Park from October 22-25, featuring marquee sets from Pretty Lights, My Morning Jacket, Excision, Geese, Unknown Mortal Orchestra, Big Gramatik (Big Gigantic & Gramatik), STS9 and host band The String Cheese Incident, among others. Frost Children’s newly announced performance will be a DJ Set.

The Warren Haynes Incident, which will take place the Saturday night of Hulaween, will be this year’s collaborative String Cheese Incident offering. Haynes, who has been in String Cheese’s orbit for decades and spent time on the road with the group as early as 1999 when his Gov’t Mule group was part of the Summer Sessions tour with SCI and other rising jambands, is expected to perform at set focused on Grateful Dead and Allman Brothers Band material. SCI has covered both acts since its earliest years. They will also dip into music from Haynes’ solo catalog and the Gov’t Mule repertoire, as well as other surprises.

Along with the latest lineup additions, Hulaween has also confirmed that guitarist Scott Metzger (Joe Russo’s Almost Dead, LaMP) and keyboardist Kyle Hollingsworth (The String Cheese Incident) will join EOTO during their show. The electronic band consists of String Cheese Incident’s Michael Travis and Jason Hann.
