Kurtis Blow
Blow began his career in New York City in the mid-1970s, when he was a breakdancer until switching to DJing and then rapping. He was the first rapper to record a full length album on a major label (1980). This occurred after recording "Christmas Rappin", his first single; during this time, "Rappers Delight" by the Sugarhill Gang became the first hit for hip hop. The whole field was derided as a fad, though, and thus there was much resistance to signing Blow.
He has appeared in the feature films Krush Groove and The Show. Bob Dylan appeared on Kurtis Blow's 1986 album Kingdom Blow. And in 2004 he recorded the song Hey Everybody with MaxC and Bomfunk MC's for their album Reverse psychology. He also co-wrote songs The Fat Boys, including their signature songs Fat Boys 1984 and The Fat Boys Are Back 1985.
