ONE805 has announced that Slightly Stoopid will join the lineup for ONE805LIVE! 2026, the benefit concert taking place Sept. 25-26, and hosted by Kevin Costner at his private oceanside estate in Carpinteria.

All proceeds from ONE805LIVE! benefit Santa Barbara County’s first responders through ONE805’s emergency grants, equipment funding and mental wellness programs.

Slightly Stoopid joins rock icons Pat Benatar & Neil Giraldo, with George Thorogood, The Fray, The Four Tops, Alan Parsons and Kevin Costner & Modern West who will also be performing at ONE805LIVE!.

“Slightly Stoopid’s appeal is massive, regularly drawing crowds of up to 20,000-plus fans per show on headline amphitheater tours and reaching roughly 3.5 million monthly listeners across streaming platforms like Spotify, according to ONE805LIVE! organizers.

Formed in Ocean Beach, San Diego in 1995 by childhood friends Miles Doughty and Kyle McDonald, Slightly Stoopid is a seven-piece powerhouse, known for its relaxed vibe and infectious grooves.

Slightly Stoopid’s signature sound layers reggae and rock with hip-hop, blues, funk and punk influences. A hallmark of its performances is the band’s seamless instrument swapping, with members trading guitars and basses midway through songs.

With 13 albums, major festival appearances from Coachella to Lollapalooza, and a devoted fanbase, Slightly Stoopid embodies the spirit of the California coast, organizers said.

“ONE805LIVE! has always been about bringing people together in support of the men and women who protect our community,” said Kirsten Cavendish Weston Smith, CEO.

“Adding Slightly Stoopid to a lineup that already includes Pat Benatar, The Fray, George Thorogood and Kevin Costner takes this year’s event to an entirely new level,” she said. “It will be an extraordinary weekend of music, purpose and community, a once-in-a-lifetime lineup in a once-in-a-lifetime setting.”

Tickets and VIP cabana packages are available at One805.org.
