Hear where moments of Kraftwerk, Enya, Herb Alpert and more ended up in producers’ deft hands.Kraftwerk.Cyril Zingaro/Keystone, via Associated PressDear listeners,Today’s playlist is a celebration of a tried-and-true method of discovering new-to-you music: identifying the samples in hip-hop songs.In his recently released book “Hip-Hop Is History,” Questlove recalls a story from his childhood that speaks to this experience. When he couldn’t fall asleep, he’d listen to the radio in the middle of the night, when D.J.s were free to play the most outré sounds. “During those years,” he writes, “I heard a song that was bizarre synth music, completely compelling, pure hypnosis on the airwaves.” He tried to tape it but could never correctly anticipate when it would come on. Several years passed and he still hadn’t figured out what that elusive song was, but then one day he heard it — or something like it — at a roller rink birthday party. When he asked about it, the D.J. was so taken with his curiosity, he gifted him the 12-inch single. “It was ‘Planet Rock,’” he writes, referencing the legendary track by Afrika Bambaataa & Soulsonic Force. “It sampled the Kraftwerk song I had heard, which I learned was called ‘Trans-Europe Express.’ That party and that 12-inch made my day, my year and part of my life.”These days it’s much easier to track down the source of a sample, thanks to Google searches, apps like Shazam and websites like the invaluable database WhoSampled.com. But samples are still powerful portals between genres, cultures and music’s past and present. Sampling is the reason Dr. Dre is one degree of separation from the Scottish composer David McCallum, and why we know that Enya is a fan of the Fugees — and vice versa.There are so many great and unexpected samples in classic hip-hop songs that today’s playlist should be considered only a brief introduction. (Perhaps a sequel will arrive in a future Amplifier, too.) If you’re a true hip-hop head, listen to the playlist before reading the descriptions below and see how many tracks you can name from hearing the source material of their samples. And if you’re more familiar with the originals than the songs that sampled them, make sure you also check out the hip-hop classics linked in the descriptions below.We so tight that you get our styles tangled,LindsayListen along while you read.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.
