Adele’s 'Rolling in the Deep' was the song that turned her into a global icon. Co-written and produced by Paul Epworth, the track was described by Adele as a 'dark disco' song. Its stomping rhythm was created by Epworth hitting a large bass drum while Adele sang her vocals in a single take to capture the raw anger of her recent breakup. The song was a massive crossover success, appealing to fans of pop, soul, rock, and even country music. It spent seven weeks at number one on the Billboard Hot 100 and was the top-selling single of 2011 in the US. It won three Grammy Awards, including Record and Song of the Year. The term 'rolling in the deep' is a slang adaptation of the British phrase 'roll deep,' meaning to have someone who has your back, though Adele repurposed it to signify the depth of her emotional turmoil.
