In the days before Gilbert O'Sullivan put rappers with uncleared samples on notice and Bad Boy made the "one track jack" an acceptable form of hitmaking, sampling was quickly becoming the creative frontier of hip-hop. Late-'80s masterpieces like 3 Feet High & Rising by De La Soul, Paul's Boutique by the Beastie Boys, and It Takes A Nation of Millions To Hold Us Back by Public Enemy stirred together dozens of appropriated sounds from older records into a dizzying, impressionistic whole that reminded some of the rock's ambitious psychedelic era of the late '60s. Unfortunately, so few current artists even attempt such a pricey method of beatmaking now that you're only going to need the phrase "sampledelic" when you're talking about those old classics.
