Adele’s 'Rolling in the Deep' was the lead single from her world-conquering album '21.' Co-written and produced by Paul Epworth, the song was born out of the anger Adele felt after her boyfriend told her she was 'weak' and that her life would be 'boring and lonely' without him. She told Epworth she wanted to record a 'dark disco' song. The driving, thumping beat was created by Epworth hitting a large bass drum to match Adele's vocal intensity. The song was a massive crossover success, reaching number one on the Billboard Hot 100 and topping charts in over 11 countries. It won Grammy Awards for Record of the Year, Song of the Year, and Best Short Form Music Video. Music critics praised the track for blending elements of soul, blues, and gospel, and for showcasing Adele’s powerful, unpolished vocal delivery that felt both vintage and modern.
