What was Adele's first single from her album '21'?

Adele’s first single from her album 21 was “Rolling in the Deep.”

Written by Adele and producer Paul Epworth, the song was released on November 29, 2010, before 21 arrived in January 2011. It served as both the album’s lead single and its opening track, immediately establishing the record’s emotionally intense sound.

The song grew from a writing session after Adele’s breakup with a former partner. Its stomping percussion, handclaps, gospel influence, and forceful vocal performance turned personal anger into a dramatic anthem. Adele described its style as a dark, bluesy, gospel-influenced song with a disco feel.

“Someone Like You” is often mistaken for the first single because it became one of Adele’s signature songs, but it was released later as the second single. “Set Fire to the Rain” followed as another major single, while “Rumour Has It” was also released later in the album campaign.
