Calvin Harris and Florence Welch’s ‘Sweet Nothing’ celebrates 14 years after becoming a UK No. 1 and one of the biggest singles from the album ‘18 Months’

Fourteen years after Calvin Harris and Florence Welch released ‘Sweet Nothing’, the collaboration remains one of the most remembered songs from the 18 Months era. Released in 2012, it brought together two artists who were already having very different but highly successful years in music, with Calvin Harris also working with Florence + The Machine around the same period. What followed gave ‘Sweet Nothing’ a much bigger story than its original release, from how the collaboration happened to the success that followed on both sides of the Atlantic.

The Story Behind ‘Sweet Nothing’

Before ‘Sweet Nothing’ became one of the most beloved songs from Calvin Harris’ 18 Months era, he and Florence Welch already had history together. Earlier in 2012, Calvin Harris remixed Florence + The Machine’s ‘Spectrum (Say My Name)’, which went on to reach No. 1 in the UK. That connection later led to an original collaboration, with Kid Harpoon joining Calvin Harris and Florence Welch as a co-writer on ‘Sweet Nothing’.

The song placed Florence Welch’s vocal in a more electronic setting than much of her work with Florence + The Machine at the time, while fitting naturally into the sound Calvin Harris was developing across 18 Months. It became part of an album that also featured collaborations with Rihanna, Ellie Goulding, Example, Kelis and Ne-Yo, helping place ‘Sweet Nothing’ within one of the most successful periods of his career.

Calvin Harris sets a Guinness World Record after performing to 1.6 million people at Bloco Skol in São Paulo, marking the largest attendance for a DJ set by a single artist

Few artists have had the kind of long-term impact on the electronic dance music scene that Calvin Harris has, with a career that has included major festival appearances at Coachella, Tomorrowland, Ultra Music Festival and Creamfields, as well as collaborations with Rihanna, Dua Lipa, Ellie Goulding and Sam Smith. His work has crossed electronic music and mainstream charts for years, but his latest achievement takes that success in a completely different direction. After performing to an estimated 1.6 million people at Bloco Skol in São Paulo, Harris has now officially earned a Guinness World Record for the largest attendance for a DJ set by a single artist.

Inside Calvin Harris’ Record-Breaking São Paulo Set

The performance took place on February 8, 2026, when Calvin Harris joined Bloco Skol during São Paulo’s pre-Carnival celebrations. The free event took over Rua da Consolação, where Calvin Harris performed from a traditional Brazilian trio elétrico near Avenida Paulista. It marked his first time performing on a trio elétrico and brought him back to Brazil after around a decade, alongside Brazilian artists Nattan, Xand Avião, Zé Vaqueiro and Felipe Amorim.

During the set, Calvin Harris wore a Brazil football shirt with “Calvinho” and the number 00 printed across the back while playing music from across his career. Guinness World Records lists This Is What You Came For, One Kiss, I Need Your Love and We Found Love among the tracks heard during the performance, as an estimated 1.6 million people gathered in central São Paulo. The Carnival setting also gave the Scottish producer a very different format from the festivals, arenas and residencies that have featured throughout his career.

A New Guinness World Record For Calvin Harris

That 1.6 million-person attendance is officially listed by Guinness World Records as the largest attendance for a DJ set by a single artist. The record page names Calvin Harris as the holder, with São Paulo, Brazil and February 8, 2026 recorded as the location and date of the achievement. The category applies specifically to a DJ set by one artist, giving the Bloco Skol performance its own place in the organization’s record database.

For additional context, Guinness World Records also notes that Madonna’s free Celebration Tour concert at Copacabana Beach in Rio de Janeiro attracted an estimated 1.6 million people on May 4, 2024. Reaching the same estimated attendance for a single DJ set puts the scale of Calvin Harris’ performance far beyond the audience size normally associated with festivals or stadium shows. Celebrating the recognition on social media, Calvin Harris wrote that he now held the world record for the category before adding, “only in Brazil!!!”

More than two decades into his career, the record gives Calvin Harris another major achievement alongside his international festival appearances, chart success and collaborations with some of the biggest names in music. His Bloco Skol performance will now be remembered not only for bringing him back to Brazil, but for attracting an audience large enough to earn a place in Guinness World Records.
