James Marriott, the Buckinghamshire songwriter whose Don’t Tell the Dog went to number one in 2025, brings his third album, Warning Signs, to OVO Arena Wembley.
James Marriott, whose album Don’t Tell the Dog went to number one in the UK in 2025, headlines OVO Arena Wembley on Friday 9 April 2027. The date follows the release of his third album, Warning Signs, by three months.
Born in Switzerland in 1997 and raised in Buckinghamshire, the son of a pianist, Marriott came to London to read modern languages at University College London. In his final year he built a YouTube following of more than two million through pop-culture commentary.
He stepped back from it to release his first single, “Slow Down”, in 2020. His debut album, Are We There Yet?, reached number 17 in 2023.
Don’t Tell the Dog, recorded at Big Jelly Studios in Ramsgate, is named after the family dog left behind in a childhood move. “California Rain” became his first top-40 single the following January, and that summer he played the main stage at Reading and Leeds.
Warning Signs follows a relationship from the rush of new desire through obsession to its aftermath. He announced the record from the stage of O2 Academy Brixton on 17 September 2026.
