In the later half of the decade, from about 1986, rap took off into the mainstream with Run-D.M.C.'s "Raising Hell", and the Beastie Boys' "Licensed to Ill", the latter becoming the first rap album to enter No.1 Spot on the "Billboard 200" and helping break down the doors for white performers to do rap. Both of these groups mixed rap and rock together, which appealed to rock and rap audiences. Hip-hop took off from its roots and the golden age hip hop flourished, with artists such as Eric B. & Rakim, Public Enemy, LL Cool J, Queen Latifah, Big Daddy Kane, and Salt-N-Pepa. Hip Hop became popular in America until the late 1990s, when it went worldwide. The golden age scene would die out by the early 1990s as gangsta rap and g-funk took over, with west-coast artists Dr. Dre, Snoop Dogg, Warren G and Ice Cube, east-coast artists Notorious B.I.G., Wu-Tang Clan, and Mobb Deep, and the sounds of urban black male bravado, compassion, and social awareness best represented by the rapper Tupac Shakur.
