AllMusic writes, "Hip-hop's golden age is bookended by the commercial breakthrough of Run–D.M.C. in 1986 and the explosion of gangsta rap with NWA in the late 80s and Dr. Dre and Snoop Doggy Dogg in 1993." However, the specific time period that the golden age covers varies among different sources. The "New York Times" also defines hip-hop's golden age as the "late 1980s and early 90s". Ed Simmons of The Chemical Brothers said, "there was that golden age of hip-hop in the early 90s when the Jungle Brothers made "Straight Out the Jungle" and De La Soul made "Three Feet High and Rising"" (though these records were in fact made in 1988 and 1989 respectively). MSNBC called the 1980s the "Golden Age" of hip-hop music. The Guardian states, "The golden age of hip-hop, from 1986 to 1993, gave the world an amazing number of great records," and also describes the period in November 1993, when A Tribe Called Quest and Wu-Tang Clan released albums, as "The Next Golden age."
