Kane Allen Brown is an American country music singer and songwriter. First garnering a mass following on social media, he released his debut extended play (EP) Closer in June 2015, and followed it up with the single, "Used to Love You Sober" in October of that year. After Brown signed with RCA Nashville in early 2016, the song was included on his second EP and major label debut, Chapter 1 in March 2016. He released his eponymous debut studio album later that year in December. The album spawned the single "What Ifs" (featuring Lauren Alaina), and in October 2017, Brown became the first artist to have simultaneous number ones on all five main Billboard country charts. Brown released his second album, Experiment, in November 2018, which became his first number one album on the Billboard 200.
