D.I.D.A.S."), Beyoncé ("Hip Hop Star"), Brooke Valentine ("Girlfight"), Sleepy Brown ("Margarita"), and Fantasia ("Hood Boy"). As a solo artist, the MC had a minor hit in 2005 with "Kryptonite (I'm on It)," one of the year's best rap singles; it was the lead single from the officially released showcase for his Purple Ribbon label, the eclectic Got Purp?, Vol. 2, which featured the likes of Killer Mike and Sleepy Brown, as well as protégé Janelle Monáe. Also involved in film (ATL, OutKast's Idlewild, Who's Your Caddy?) and even the stage (he worked with the Atlanta Ballet in 2008), Big Boi prepped his first solo album, the loose and rollicking Sir Lucious Left Foot...The Son of Chico Dusty, which was released on Def Jam in July 2010. It debuted at number three on the Billboard 200 chart. Vicious Lies and Dangerous Rumors, issued in December 2012, was just as packed with guest appearances but extended far beyond the realm of rap to involve the likes of Little Dragon, Wavves, and Phantogram. ~ Andy Kellman
