Leftover Salmon have announced Arch Deluxe, a two-day music-focused block party in St. Louis’ Gateway to the West. The upcoming gathering is scheduled for May 1-2, 2026, and features a roster of special guests who have signed on to perform at the late-spring festival.
According to the band’s social media announcement, the block party will take place in the heart of the city. It will feature a stacked lineup of talented musicians and acts, including the Mountain Grass Unit, Horseshoes & Hand Grenades, The Hillbenders, Falling Fences, Clusterpluck, Moon Valley, Front Port, Silas Herman and The Tone Unit, Justin Rose & The Green Thumbs, Haelnhoj, Barnum Jack, and Scroggins & Farrar.
The group’s St. Louis event will arrive after their fourth annual High Country Kaua’i event on April 17-19, 2026, at the Porter Pavilion at Anaina Hou Community Park in Kilauea, Hawaii. The island occasion will include three nights of Leftover Salmon, as well as special guest appearances by Sam Bush, Holly Bowling, Jason Carter, Bronwyn Keith-Hynes, and Andy Thorn, who will play a special Mac Miller set.
