Colorado’s summer concert calendar just added a major reggae-rock summit.
Sublime, Slightly Stoopid, and 311 will join forces for Summer Greens 2026, set for Friday, August 7 at Fiddler’s Green Amphitheatre in Greenwood Village, Colorado. The event is presented by AEG Presents.
According to the official event details, doors open at 4:00 PM with the show beginning at 5:00 PM. Tickets go on sale Friday, February 27 at 10:00 AM MT via AXS, with in-person purchases available at select AEG box offices along the Front Range.
The triple bill brings together three of alternative music’s most commercially durable acts. Sublime continue their modern era with Jakob Nowell fronting the band alongside original member Eric Wilson. Slightly Stoopid remain one of reggae-rock’s most consistent summer headliners, while 311 bring decades of genre-blurring hits to the amphitheater stage.
Full ticketing information is available through AXS and AEG Presents.
