40. Kurtis Blow, 'The Breaks'
Non-album single, 1980
The first rap hit on a major label, peaking at Number 87, was a no-frills joint: a loping bass line and jumping beat with the Harlem-born Blow presiding over playground-party noises and percussion breakdowns. Blow toured extensively behind "The Breaks," taking B-boy culture to mainstream USA while blazing a trail for rappers like Run of Run-DMC, who got his start billing himself "The Son of Kurtis Blow."
