The Idaho Botanical Garden has unveiled the initial lineup for its 2026 Outlaw Field Summer Concert Series, featuring a mix of reggae, folk-rock, and blues artists set to perform at the intimate 4,000-seat outdoor venue. The concert series, which has been a Treasure Valley favorite since 2008, will kick off on June 12 with Iration and Tribal Seeds, followed by performances from Kaleo, Rainbow Kitten Surprise, and the legendary Bonnie Raitt.

Why it matters

Outlaw Field has become a beloved summer destination for music lovers in the Boise area, offering an intimate garden setting with a stunning foothills backdrop and a quirky history that dates back to the site's former use as a recreation field for the Old Idaho Penitentiary. The venue's diverse lineup and affordable concessions policy, which allows attendees to bring in their own food and non-alcoholic beverages, have made it a unique and popular alternative to larger amphitheaters in the region.

The details

Outlaw Field, which can accommodate up to 4,000 concertgoers, attracted nearly 60,000 attendees and hosted 17 shows during the 2025 season. The venue's name pays homage to its history as the former recreation field for the Old Idaho Penitentiary, which closed its doors more than 50 years ago. In addition to the diverse musical acts, Outlaw Field is known for its affordable concessions policy, which allows attendees to bring in their own food and sealed, non-alcoholic beverages.

• The 2026 Outlaw Field Summer Concert Series will kick off on June 12.
