in 1982, taylor, who was inspired by kraftwerk's futuristic electronic music, debuted at the roxy a test cassette of ebn-ozn's ground breaking, 12-inch white rap/spoken word "aeiou sometimes y". it was the first commercially released american single ever made on a computer, a fairlight cmi, ushering in the era of music computer sampling. in that same year, bambaataa and soulsonic force stopped performing with a live band, and began to use only technology. bambaataa credited the pioneering japanese electropop group yellow magic orchestra, whose work he sampled, as an inspiration. he also borrowed a keyboard hook from german electronic pioneers kraftwerk and was provided the electronic roland tr-808 "beat-box" by producer arthur baker and synthesizer player john robie. that resulted in "planet rock," which went to gold status and generated an entire school of "electro-boogie" rap and dance music. bambaataa formed his own label to release the time zone compilation. he created "turntablism" as its own subgenre and the ratification of "electronica" as an industry-certified trend in the late 1990s.
