Rihanna's demo was shipped out to Def Jam Recordings, where Jay Brown, an A&R executive at the record label, was one of the first to hear the demo.Brown played the demo tape for rapper Jay-Z, who had recently been appointed as president and Chief executive officer (CEO) of Def Jam.She grew up in a three-bedroom bungalow in Bridgetown and sold clothes with her father in a stall on the street.Rihanna's childhood was deeply affected by her father's addiction to crack cocaine and alcohol, which contributed to her parents' strained marriage.She recorded the demo over the next year intermittently, due to only being able to record during school holidays."Pon de Replay" and "The Last Time" were two tracks recorded for the demo tape, which were eventually included on her debut album Music of the Sun.
She waited in Jay-Z's office until three in the morning to get lawyers to draft up a contract because he wanted to prevent her from signing with another label.
Its lead single "Umbrella" became an international breakthrough in her career, as she won her first Grammy Award at the 50th Annual Grammy Awards in 2008.
She then annually released four consecutive RIAA multi-platinum certified studio albums, including the Grammy Award winner Unapologetic (2012).
As a child, she went through a lot of CT scans for the excruciating headaches she suffered: "[The doctors] even thought it was a tumor, because it was that intense." She attended Charles F.
Broome Memorial Primary School and Combermere High School, where she studied alongside future England cricketer Chris Jordan and future West Indies cricketer Carlos Brathwaite.
