Following the decline of disco music in the late 1970s, various funk artists such as Zapp & Roger began experimenting with talk boxes and the use of heavier, more distinctive beats. Boogie played a role during the formative years of electro, notably "Feels Good" by Electra (Emergency – EMDS-6527), the post-disco production "You're the One for Me" by D. Train (Prelude – PRL D 621), and the Eric Matthew/Darryl Payne productions "Thanks to You" by Sinnamon (Becket – BKD 508), and "On A Journey (I Sing The Funk Electric)" by Electrik Funk (Prelude – PRL D 541). Electro eventually emerged as a fusion of different styles, including funk, boogie combined with German and Japanese technopop, in addition to influences from the futurism of Alvin Toffler, martial arts films, and video game music. The genre's immediate forebearers included Kraftwerk and Yellow Magic Orchestra (YMO).
