Calvin Harris gets Rock in Rio crowd dancing in the rain

Rain did not stop 100,000 people from dancing at Rock in Rio. Calvin Harris turned Sunday's wet festival grounds into a giant dance floor during a day built around pop, rock, R&B, hip-hop and electronic music.

The lineup also featured Black Eyed Peas, Nelly, Ne-Yo, Jota Quest, BaianaSystem and Barão Vermelho. Their dance-oriented sets marked a sharp change from the festival's first two days, which focused on classic and heavy rock.

The weather changed the look of the crowd as well. Black clothing and metal accessories gave way to white rain capes during an unusually cold, drizzly day in Rio, with rain affecting the concerts from the first performance to the last.

Harris was the day's biggest draw. The 42-year-old Scottish DJ became the first DJ to serve as the main attraction on a Rock in Rio day in the festival's 41-year history, a position traditionally reserved for legendary bands. His appearance sold out first among this year's festival entries, driven by global hits including "Outside," "Summer" and "We Found Love," each of which has surpassed one billion Spotify streams.

His set included sound effects, visuals and fireworks, opening with "Sweet Nothing," "Pray to God" and "Outside." He also performed songs created with Rihanna, Dua Lipa and Sam Smith. Black Eyed Peas kept the crowd moving with "I Gotta Feeling," "Where's the Love?" and other hits. The group, consisting of will.i.am, apl.de.ap and Taboo, returned to the Rio festival after appearing there in 2019.
