Twenty Years of Slam Dunk: Hatfield releases its most ambitious Southern edition yet

Slam Dunk Festival celebrated its 20th anniversary at Hatfield Park, drawing in 30,000 alternative music fans over the May Bank Holiday weekend. The scorching weather didn’t deter the crowd from enjoying the festivities, as they eagerly gathered in the wide-open Slam Dunk arena to witness the spectacle.

One notable change for the 2026 festival was the introduction of two separate stages, each with its own left and right sides. This setup allowed for continuous performances, with one side setting up while the other was in full swing. The seamless transitions between sets meant more bands could be accommodated throughout the day, giving attendees more opportunities to rock out and mosh in the pulsating atmosphere.

The event kicked off with Call Me Amour taking the stage at the Key Club, showcasing a heavier sound with their new drummer and debuting their latest track ‘Wrong Direction.’ Meanwhile, Unpeople captured the audience’s attention on Main Stage West with their infectious pop style and captivating harmonies. Their performance of ‘Clouds’ highlighted the band’s versatility, blending catchy melodies with occasional heavy breakdowns to create a dynamic and engaging set. Unpeople’s presence at Slam Dunk South hinted at a promising future for the band, with their rise in the UK music scene set to continue throughout the year.

The Key Club stage also delivered a diverse lineup, featuring Japanese alt-metallers SiM (Silence iz Mine) who seamlessly fused multiple rock genres in their electrifying performance. From reggae to metalcore to punk, SiM’s eclectic sound kept the audience on their toes, delivering a unique and captivating musical experience.

Overall, Slam Dunk Festival’s 20th anniversary edition at Hatfield Park proved to be a thrilling and unforgettable experience for music enthusiasts. The festival’s innovative stage setup, diverse lineup, and energetic performances set the bar high for future events, promising more chaos and excitement in the coming summer months. With a successful run in 2026, Slam Dunk Festival continues to solidify its position as a must-attend event for alternative music fans looking to celebrate the best of the genre in a vibrant and immersive setting.
