The Chemical Brothers' 25-year loop
The electronic duo's most recent studio album, 2023's For That Beautiful Feeling, earned a four-star review from NME, which praised its mix of dancefloor bangers and psychedelic experiments and said the duo remained industry leaders ten albums into their career. The album led to a UK and Ireland tour in late 2023, followed by dates in Japan, New Zealand and Australia in early 2024, and a Teenage Cancer Trust show at London's Royal Albert Hall that March.
The pair have continued playing DJ sets together in recent years, including at San Francisco's Portola Festival in 2025. Rowlands also launched a new project, TOMORA, with AURORA in late 2025; their debut album Come Closer arrived earlier this year alongside a 2026 UK and European tour announcement, with a new EP, Celebration, set for October 16. Separately, their 2015 single "Go" saw a 429% streaming boost and briefly returned to the UK Top 10 after being featured in the Netflix film Apex.
Other newly added acts' latest news
Ellie Goulding released her sixth album, I Know Too Much, last month, following 2023's Higher Than Heaven; she has described it as honestly pulling everything together, "like writing a diary through music." Slovak singer ADÉLA is touring behind her debut album PRIMA, which earned a four-star NME review last month calling her a "pink-haired pop newcomer."
5 Seconds Of Summer will perform material from their sixth album, EVERYONE'S A STAR!; Underscores' latest album, U, received a five-star NME review, described as "hyperpop for an overstimulated, isolated generation."
