I Am... Tour was the fourth concert tour by American performer and singer-songwriter Beyoncé Knowles, in support of her third studio album, I Am... Sasha Fierce (2008), consisting of 110 concerts across six continents. Two months of preparations for the tour began eight months prior to its commencement, with daily twelve-hour rehearsals. The tour was announced in October 2008, and began in March 2009 with five preliminary ’rehearsal’ shows in North America. Knowles has described the I Am... World Tour as her best and most theatrical of all of her tours.
