4 is the fourth studio album by American recording artist Beyoncé Knowles, released through Columbia Records on June 24, 2011. Three weeks before its scheduled release, 4 had leaked onto the Internet. The twelve-song set (eighteen on the deluxe edition) marks the first release by Knowles since separating professionally with father and manager, Mathew, in March 2011. In 2010, Knowles took a break from her career to rest and gain perspective. During the hiatus, she dedicated herself to enjoying the everyday things in life, which she claims reignited her creativity and became a source of inspiration. Knowles also drew inspiration from Fela Kuti, Earth, Wind & Fire, Lionel Richie, with additional influences from The Jackson 5, New Edition, Florence and the Machine, Adele, and Prince, among others.
