On their next two albums, ATLiens (1996) and Aquemini (1998), Outkast experimented with their sound by adding elements of trip hop, soul, and jungle. The albums were also influenced by a return to traditional black music genres, with funk being the most prominent example. Outkast's style and lyricism again received commercial and critical acclaim. With the duo's portrayal of themselves as out-of-place extraterrestrials in ATLiens, Benjamin's lyrics, in particular, were noted for their surreal, space-age tinge: "the funkadelic, futuristic, and seemingly unfamiliar, weird, or eccentric persona projected by André 3000 creates the chance to transcend the more pronounced characterizations of gangstas and pimps so regularly assumed by black men rap artists. " During the recording of these albums, Benjamin took up guitar, painting, and a relationship with singer Erykah Badu.
