Rapper Nas was joined by Lauryn Hill and Damian Marley during his second weekend performance at the 2014 Coachella music festival in California on Saturday night (19Apr14). To celebrate the 20th anniversary of the One Mic hitmaker's debut album Illmatic, he invited Marley to perform their 2005 collaboration Road to Zion as well as the reggae singer's hit song Welcome to Jamrock. R&B songstress Hill thrilled fans when she teamed up with the rapper on the Fugees' Ready or Not and If I Ruled The World, her duet with Nas. The set came one week after the 40 year old hit the stage with former rival Jay Z to perform a rendition of Dead Presidents II during the first weekend (11-13Apr14) of Coachella. Jay Z was a special guest again on Saturday (19Apr14), but this time he helped close out Pharrell Williams' star-studded set by performing Frontin', Excuse Me Miss, La La La (Excuse Me Miss Again), and I Just Wanna Love U (Give it 2 Me). Williams also brought out T.I., Usher and Clipse frontman Pusha T as part of his hits-laced performance at the annual festival in the desert. T.I. performed Blurred Lines with the Grammy winner, while Usher hit the stage for a rendition of U Don't Have to Call, and Pusha T took on his hit, Grindin', with Williams. Rapper Busta Rhymes also joined the headliner for the second weekend in a row to perform Pass The Courvoisier Pt 2. The gig followed Williams' cameo-filled performance last weekend (12Apr14), when he brought out Gwen Stefani, Rhymes, Nelly, Sean 'Diddy' Combs, Diplo and Snoop Dogg.
