Bassist Mike Gordon of Phish will lead his band of Scott Murawski, Craig Myers, Robert Walter and John Kimock to this weekend’s Suwannee Hulaween festival in Live Oak, Florida. Gordon recently revealed a pair of guests who will join the quintet at The Spirit Of The Suwannee Music Park.

Mike Gordon will perform on the Amphitheater Stage on Friday afternoon starting at 4 p.m. ET. The bassist took to Twitter to announce the five-piece will be aided by Emily Elbert and Madi Diaz. Elbert is a Los Angeles soul-folk artist who recently spent a year as a member of Esperanza Spalding’s experimental music and theater project, “Emily’s D+Evolution.” She also contributed to Dweezil Zappa’s LP of original music, Via Zammata. Diaz is also a singer-songwriter based out of Los Angeles.
