Spafford made their debut performance at Suwannee Hulaween last weekend, playing two full sets to excited fans at the Spirit of Suwannee Music Park in Live Oak, Florida. Their breakthrough appearance culminated with a Saturday late-night set on the Spirit Lake stage, which brought a very special guest along with them. Following sets from Damian “Jr. Gong” Marley, Run The Jewels, and The Disco Biscuits, Spafford stepped up for what would become one of the highlights of the night.

Ridiculous set-opening versions of “The Postman” and “Todd’s Tots” proved to be just a warm-up for the Saturday late night set, as keyboardist Aron Magner of The Disco Biscuits then walked on stage, joining the band for an extended segment that took “Mind’s Unchained” into Spafford’s arrangement of “Mad World” by Tears For Fears. The impressive cover was played impeccably by Aron Magner, who slotted right in on the keys next to Red Johnson for one of the standout jams of the weekend. Even Magner’s Biscuits bandmate Marc Brownstein was feeling the collab, starting an “it’s a Maaag-neeer” chant from the crowd over the band’s song-ending “it’s a maaad world” refrain.
