The Jungle Brothers' 1988 debut, Straight Out The Jungle, was a landmark release in the development of conscious hip-hop. That album's successor, 1989's superior Done By The Forces Of Nature, builds on the innovations of the group's debut and adds the polish of major label production under the steady eye and ear of Kool DJ Red Alert, the works executive producer. The Jungle Brothers major label debut offered a spiritual take on black America that was as mellow as it was playful. Though the Jbeez sonic affiliation with the underground is still intact, the album is cleaner, less dated, and generally easier on the ears than the independently released Straight Out The Jungle. The group's sophomore effort is a vivid tapestry of buoyant beats; sampling from jazz, world music, classic funk, R&B and even house and club style beats (seldom heard in hip-hop). The raps remain centered primarily on the Afrocentric themes for which the Native Tongues posse (De La Soul, A Tribe Called Quest, Queen Latifah) was well-known ("Acknowledge Your Own History" and Black Woman are strong examples), but the group's seriousness does not dismiss their need for more light-hearted, rump-bumping fun (see: "What U Waitin' For," "Belly Dancin' Dina"). Smart, witty, and musically sophisticated, but never a commercial smash, the Jbeez remain one of rap's most influential groups, and this excellent set proves why.
