Tom Grennan has today announced the GRENNAN ‘25 tour – his biggest ever arena tour – will be coming to The O2 on Saturday 6 September 2025.

The GRENNAN ‘25 tour comes alongside the announcement of the multi-platinum-selling artist’s fourth album ‘Everywhere I Went Led Me To Where I Didn't Want To Be’ and the unveiling of new single ‘Shadowboxing’. The 15-track album serves as the eagerly awaited follow-up to 2023’s ‘What Ifs & Maybes’ and is set for release on August 15th through Insanity Records.

The GRENNAN ’25 arena tour and album news come hot on the heels of Tom Grennan’s Top 3 festive smash ‘It Can’t Be Christmas (Amazon Music Original)’ which immediately gained silver certification in its first run at the Christmas title. Tom achieved his highest ever singles chart for a solo release and was only narrowly held off the top spot by Christmas titans Wham! and Mariah Carey.

With two number one albums under his belt alongside multiple Brit and Ivor Novello nominations, countless airplay smashes, sold-out arena tours and an MTV Award for Best UK Act, Tom Grennan is already one of the country’s biggest artists. Last August saw the Bedford-born artist headline his biggest show to date to a capacity crowd of 25,000 at Gunnersbury Park.

Now he’s readying to take things to a whole new level still with a state-of-the-art pop album made with Justin Tranter. Keen to explore a new sound, Tom enlisted the songwriter and producer behind hits for Britney Spears, Linkin Park, Dua Lipa and Fall Out Boy and found in Tranter a collaborator who understood exactly what he wanted to say and what he wanted to sound like: George Michael, Prince, Freddie Mercury. “So much of the new music is uplifting — it makes you dance, makes you sing,” Tom says.

‘Shadowboxing’ is the second song to be unveiled from Tom’s forthcoming album following the release of slick, upbeat single ‘Higher’ in September, and was the first song he and Justin Tranter wrote together. “It represents what the whole album is about,” Tom explains. “It's about my fight with a side of me I have a lot of trouble with. It’s still a daily battle. But I’ve learned how to fight all these demons and I’m mentally and physically prepared now. I’m in athlete mode.”

While the title alludes to a time when Tom faced challenges with his mental health, ‘Everywhere I Went Led Me To Where I Didn't Want To Be’ is a positive album about self-belief and having the confidence to take risks. “This album is about me, revived. Now I'm at a place where I DO want to be. And I'm ready to blow people's heads off.”

It sees the evolution of one of UK’s most exciting talents at his creative best and is set to be a stunning addition to Tom Grennan’s already-impressive discography, which has seen him accumulate over 1.5 million album sales and 2.5 billion streams across his gold-selling debut Lighting Matches (2018), his first UK Number One album Evering Road (2021) and What Ifs & Maybes (2023), another Number One and Tom’s third gold-selling album in a row. That third album was also, he says, an early hint of what was to come. “It was the first time I thought: ‘I don't want to just be a singer-songwriter’,” he remembers. “It established the foundation for where I am with this album.”
