American Express presents BST Hyde Park has expanded the lineup for Maroon 5’s highly anticipated festival debut on Friday 3 July. A wave of new artists will join the multi-platinum headliners in London, alongside previously announced special guests OneRepublic, Jess Glynne, Ella Eyre, and Only The Poets.
Among the newly added acts is English singer-songwriter Bradley Simpson. Best known as the frontman of pop-rock band The Vamps, Simpson launched a successful solo career with his indie-leaning debut album The Panic Years. Joining him is VOILÀ, the Los Angeles-based indie-pop duo consisting of Luke Eisner and Gus Ross, who have captured over 335 million global streams with their self-produced tracks.
The bill also welcomes rising solo artist Pedro Santos, formerly of the boyband Here At Last, whose latest single "Lady In Red" has surpassed 2.5 million streams. Irish indie-rock outfit Dylan Flynn & The Dead Poets will bring their widescreen, DIY sound to Hyde Park following sold-out shows across the UK and Ireland and a recent appearance at SXSW.
Rounding out the latest announcement are Scottish singer-songwriter Pat Hamilton, who has built a loyal following through his genre-blending debut album To Whom It May Concern, and South East London R&B artist Stefan Mahendra, known for his rich gospel and Motown-inspired soul music.
The celebration forms part of another major summer for BST Hyde Park, which features an extensive series of world-class headliners. The 2026 festival lineup includes Garth Brooks, ATEEZ, Mumford & Sons, Duran Duran, Pitbull, and Lewis Capaldi. Final tickets for Maroon 5’s headline day are currently on sale.
