The feminism and female empowerment themes on Beyoncé's second solo album B'Day were inspired by her role in Dreamgirls and by singer Josephine Baker. Beyoncé paid homage to Baker by performing "Déjà Vu" at the 2006 Fashion Rocks concert wearing Baker's trademark mini-hula skirt embellished with fake bananas. Beyoncé's third solo album I Am... Sasha Fierce was inspired by Jay Z and especially by Etta James, whose "boldness" inspired Beyoncé to explore other musical genres and styles. Her fourth solo album, 4, was inspired by Fela Kuti, 1990s R&B, Earth, Wind & Fire, DeBarge, Lionel Richie, Teena Marie with additional influences by The Jackson 5, New Edition, Adele, Florence and the Machine, and Prince.
